Homogeneous combustion catalysts for efficiency improvements and emission reduction in diesel engine
Publisher: Wiley
Date: 16-07-2015
DOI: 10.1002/9781118991978.HCES016
Abstract: This article presents an innovative catalytic technology of the use of ferrous‐picrate‐based homogeneous combustion catalysts that can be easily applied to improve fuel efficiency and reduce pollutant emissions from diesel engines. The homogeneous combustion catalysts, also referred to as fuel performance catalysts ( FPC ), can be dosed into the diesel at merely trace levels and are capable of improving fuel efficiency and reducing the emissions of smoke, unburned hydrocarbons, and carbon monoxide from diesel engines, which is supported by numerous laboratory diesel engine tests and field trials. The use of the catalysts enhances the fuel combustion rate and leads to more complete combustion and smaller sizes of primary soot particles and aggregates, which have lower ignition temperature and higher oxidative reaction rates. The catalysts are also capable of improving the fuel efficiency of biodiesel combustion in diesel engines. A s le case study of the economic and environmental benefits of this catalytic technology is also presented at the end of this article to illustrate the very significant benefits to be gained should the catalyst be widely adopted.

Thermal stability and kinetics of decomposition of ammonium nitrate in the presence of pyrite

DOI: 10.1016/J.JHAZMAT.2008.10.054
Abstract: The interaction between ammonium nitrate based industrial explosives and pyrite-rich minerals in mining operations can lead to the occurrence of spontaneous explosion of the explosives. In an effort to provide a scientific basis for safe applications of industrial explosives in reactive mining grounds containing pyrite, ammonium nitrate decomposition, with and without the presence of pyrite, was studied using a simultaneous Differential Scanning Calorimetry and Thermogravimetric Analyser (DSC-TGA) and a gas-sealed isothermal reactor, respectively. The activation energy and the pre-exponential factor of ammonium nitrate decomposition were determined to be 102.6 kJ mol(-1) and 4.55 x 10(7)s(-1) without the presence of pyrite and 101.8 kJ mol(-1) and 2.57 x 10(9)s(-1) with the presence of pyrite. The kinetics of ammonium nitrate decomposition was then used to calculate the critical temperatures for ammonium nitrate decomposition with and without the presence of pyrite, based on the Frank-Kamenetskii model of thermal explosion. It was shown that the presence of pyrite reduces the temperature for, and accelerates the rate of, decomposition of ammonium nitrate. It was further shown that pyrite can significantly reduce the critical temperature of ammonium nitrate decomposition, causing undesired premature detonation of the explosives. The critical temperature also decreases with increasing diameter of the blast holes charged with the explosive. The concept of using the critical temperature as indication of the thermal stability of the explosives to evaluate the risk of spontaneous explosion was verified in the gas-sealed isothermal reactor experiments.

NH3 as a Transport Fuel in Internal Combustion Engines: A Technical Review
Publisher: ASME International
Date: 11-03-2019
DOI: 10.1115/1.4042915
Abstract: Ammonia (NH3) is an excellent hydrogen (H2) carrier that is easy to bulk manufacture, handle, transport, and use. NH3 is itself combustible and could potentially become a clean transport fuel for direct use in internal combustion engines (ICEs). This technical review examines the current state of knowledge of NH3 as a fuel in ICEs on its own or in mixtures with other fuels. A particular case of interest is to partially dissociate NH3 in situ to produce an NH3/H2 mixture before injection into the engine cylinders. A key element of the present innovation, the presence of H2 is expected to allow easy control and enhanced performance of NH3 combustion. The key thermochemical properties of NH3 are collected and compared to those of conventional and alternative fuels. The basic combustion characteristics and properties of NH3 and its mixtures with H2 are summarized, providing a theoretical basis for evaluating NH3 combustion in ICEs. The combustion chemistry and kinetics of NH3 combustion and mechanisms of NOx formation and destruction are also discussed. The potential applications of NH3 in conventional ICEs and advanced homogenous charge compression ignition (HCCI) engines are analyzed.
Combined heat and power generation using gas engines fuelled with pyrolysis gas
Publisher: Wiley
Date: 16-07-2015
DOI: 10.1002/9781118991978.HCES005
Abstract: This article describes the technology for combined heat and power ( CHP ) generation using gas engines fueled with synthetic gaseous fuels from pyrolysis of biomass and municipal solid wastes (MSWs). The main pyrolysis gases of biomass and MSWs are carbon monoxide, carbon dioxide, methane, and an appropriate amount of hydrogen to improve the ignition quality. The yield of these gaseous products can be controlled by adjusting the operating parameters such as solid retention time, pyrolysis temperature, heating rate, and vapor phase residence time. Biochar, a by‐product of pyrolysis, is an effective catalyst to crack tar to increase the yield of the pyrolysis gas. After cleaning and conditioning, the pyrolysis gas can be directly used in the gas engines for CHP generation with high efficiency, flexibility, and low investment, particularly in the low‐power output range, typically less than 5 MW .
Distributed Energy Systems Based on Water Electrolysis Driven by Renewable Electricity
Publisher: Wiley
Date: 16-07-2015
DOI: 10.1002/9781118991978.HCES008
Abstract: Renewable electricity such as wind and solar power provides a meaningful sustainable energy source for remote regions, but its intermittency in nature and inherently low power intensities and energy densities require suitable energy storage mechanisms to make it viable. Alkaline water electrolysis can serve as such a means of energy storage. This article outlines a distributed energy system concept involving water electrolysis. The promises of the distributed energy system are discussed in terms of the development and research of water electrolysis. The technical studies for water electrolysis were evaluated and assessed with current literature. By analyzing the opportunities and limitations of water electrolysis in matching their power scales with feasible renewable electricity sources, this work showed that a distributed energy system with a capacity of 200 kW is technically and economically feasible using currently available technologies, indicating the potential of this distributed system for energy supply for remote communities. This work also identifies several key areas where further R& D effort is needed in order to help deploy water electrolysis and hydrogen fuel cell technologies in the utilization of renewable energy.

The effect of Al2O3, CeO2, and ZrO2 on the performance of Cu/ZnO catalyst in methanol synthesis from biomass pyrolysis syngas

DOI: 10.1615/INTERJENERCLEANENV.2022045582
Abstract: The effect of Al sub /sub O sub /sub , CeO sub /sub , and ZrO sub /sub as promoters on the catalytic activity of a Cu/ZnO catalyst for methanol synthesis from biomass pyrolysis syngas was investigated. The catalysts were prepared using a coprecipitation method, with the wt.& #37 ratio of Cu:Zn:M & #61 68:28:4 (M & #61 Al, Ce, and Zr). The activity of the catalysts was tested to determine the most appropriate promoter for the Cu/ZnO catalyst to accommodate methanol production from low stoichiometric number (S sub N /sub ) syngas. The experiment was performed in a continuous flow fixed bed reactor at 513 K, 4 MPa, gas hourly space velocity (GHSV) of 2000 h sup -1 /sup , and 24 h time on stream using simulated biomass pyrolysis syngas with a composition of 25& #37 H sub /sub , 25& #37 CO, 20& #37 CH sub /sub , 20& #37 CO sub /sub ,10& #37 N sub /sub (S sub N /sub & #61 0.111). The effluent gas was analyzed every 6 h using gas chromatography to determine the conversion of gases and production of hydrocarbons. The catalysts were characterized by N sub /sub adsorption/desorption, Powder X-ray Diffraction (XRD), and Temperature Programmed Reduction of hydrogen (H sub /sub -TPR) techniques. It was found that the promoter in Cu/ZnO-based catalysts plays a crucial role in the methanol selectivity and catalysts stability, yet does not significantly affect feed conversion. Nevertheless, the findings will significantly contribute to developing a robust catalyst that can be used for a direct route for methanol production from biomass pyrolysis syngas.

A Two-Phase Anaerobic Digestion Process for Biogas Production For Combined Heat and Power Generation for Remote Communities
Publisher: Wiley
Date: 16-07-2015
DOI: 10.1002/9781118991978.HCES003
Abstract: In a conventional anaerobic digestion ( AD ) process, a feedstock rich in organic matters is converted to a combustible gas, known as biogas , containing mainly methane ( CH 4 ) and carbon dioxide, under the action of microorganisms such as methanogenic microbes in the absence of oxygen. However, the conventional AD process is slow and difficult to control for optimal biogas production. A two‐phase anaerobic digestion (T‐ PAD ) process is a sequential anaerobic process, in which hydrogen and CO 2 are produced in the first phase and methane and CO 2 are produced in the second phase. The two streams are then combined to form a hydrogen‐enriched biogas, which has a much improved ignition quality if used in gas engines for combined heat and power ( CHP ) generation, an emerging technology especially for off‐the‐grid remote energy services. This article describes the principles of the T‐ PAD process, provides a sound technical procedure and engineering protocol for designing and integrating the T‐ PAD into a CHP system, and completes with an illustration of the working of a case study of a pilot‐scale process demonstration unit.

The Relationship Between Structural and Catalytic Activity of α and γ-Bismuth-Molybdate Catalysts for Partial Oxidation of Propylene to Acrolein
Publisher: World Scientific Pub Co Pte Lt
Date: 04-2003
DOI: 10.1142/S0218625X03005153
Abstract: Bismuth-molybdate catalysts are known to be effective for catalytic partial oxidation of propylene to acrolein. Their properties and the kinetics and reaction mechanisms for acrolein production have been extensively studied, especially in their basic forms, such as α, β, and γ-bismuth-molybdate. Although the reaction mechanisms have been reported widely in the literature, a general agreement has not been reached, especially from a catalyst-structure point of view. The present contribution reports an effort to understand the structural changes of α and γ-bismuth-molybdate catalysts at varying temperatures as examined using high temperature XRD and to relate the catalyst performance (activity and selectivity) for propylene partial oxidation to acrolein. The XRD analysis was performed at temperature between 250 and 450°C in ambient atmosphere and the Rietveld refinement method was used to extract unit cell parameters. The results showed a distinct similarity between the shapes of the thermal expansion of the catalysts and their activity and selectivity curves, indicating a significant role that the catalyst interatomic structure plays in the overall reaction mechanism.

POWER GENERATION AND RECOVERY OF HIGHER HYDROCARBONS UTILIZING COLD ENERGY DURING LNG REGASIFICATION
Publisher: Begell House
Date: 2023
DOI: 10.1615/INTERJENERCLEANENV.2023046661
Abstract: Liquefied natural gas (LNG) is stored and transported at cryogenic temperatures below -162& #176 C. Despite the significant potential of the ultralow-temperature energy inherent in LNG for various applications, it is frequently squandered during regasification. While previous studies have proposed utilizing LNG cold energy for power generation and hydrocarbon recovery, none have explored the combined applications of these processes. Therefore, this study aims to leverage LNG cold energy during regasification for simultaneous power generation and natural gas liquids (NGL) recovery. Different power generation configurations using the Rankine and Brayton cycles are reviewed and compared to identify the most suitable power cycles and working fluid candidates. Different configurations for NGL recovery are also examined to optimize the utilization of LNG cold energy. The preliminary results of the proposed system are obtained using Aspen HYSYS software, incorporating natural water sources at ambient temperature as the heat source. The proposed system effectively produces ethane and liquefied petroleum gas (LPG), meeting the required sales gas specifications while generating an overall net power output. Furthermore, this paper investigates the impact of ambient temperature on process efficiency, providing valuable insights into the system's performance under different environmental conditions.

Rheological Properties and Stability Characteristics of Biochar-Algae-Water Slurry Fuels Prepared by Wet Milling
Publisher: ASME International
Date: 08-05-2019
DOI: 10.1115/1.4043551
Abstract: This study was aimed to understand the rheological properties and stability characteristics of biochar-algae-water (BAW) slurry fuels prepared by wet milling. A pine sawdust biochar and a chlorella vulgaris algae were used in preparing the slurry fuels. The BAW slurries were formulated by mixing the biochar, algae, de-ionized water, lignosulfonic acid sodium salt, and then the mixture was ball-milled for various times. The BAW slurries with a constant solid loading of 45 wt % were prepared with varied algae proportion in algae/biochar mixture. The apparent viscosity and stability of BAW slurries were measured. It was found that D50 of the particles of the solid in the slurries decreased with increasing milling time. The viscosity of the slurries decreased first and then increased as milling time increased, reaching a minimal value when D50 of the solid was between 3 and 7 μm. The lowest viscosity of BAW slurries achieved at a given solid loading increased with increasing the algae proportion in the solid. The BAW slurries showed better stability at higher algae proportions due to enhanced flocculation.

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMR.518-523.2456
Abstract: CuO/TiO 2 , CuO/Ti 0.9 Ce 0.1 O 2 and CuO/CeO 2 /TiO 2 composite catalysts were prepared and tested for their application in selective catalytic reduction (SCR) of NO with C 3 H 6 . The effect of CeO 2 species on the catalytic performance was further evaluated. Catalyst characterization including BET surface area, XRD and temperature-programmed reduction of H 2 (H 2 -TPR) suggested that the addition of CeO 2 species changed the physicochemical properties of the catalysts obtained. Compared to the impregnation method, the homogeneous precipitation method was an effective approach to preparing the CeO 2 doped catalyst, which could promote the activation of C 3 H 6 to react with NO.
Conversion of hexose into 5-hydroxymethylfurfural in imidazolium ionic liquids with and without a catalyst
Publisher: Elsevier BV
Date: 05-2011
DOI: 10.1016/J.CARRES.2011.03.015
Abstract: Conversion of fructose and glucose into 5-hydroxymethylfurfural (HMF) was investigated in various imidazolium ionic liquids, including 1-butyl-3-methylimidazolium chloride (BmimCl), 1-hexyl-3-methylimidazolium chloride (HmimCl), 1-octyl-3-methylimidazolium chloride (OmimCl), 1-benzyl-3-methylimidazolium chloride (BemimCl), 1-Butyl-2,3-dimethylimidazolium chloride (BdmimCl), and 1-butyl-3-methylimidazolium p-toluenesulfonate (BmimPS). The acidic C-2 hydrogen of imidazolium cations was shown to play a major role in the dehydration of fructose in the absence of a catalyst, such as sulfuric acid or CrCl(3). Both the alkyl groups of imidazolium cations and the type of anions affected the reactivity of the carbohydrates. Although, except BmimCl and BemimCl, other four ionic liquids could only achieve not more than 25% HMF yields without an additional catalyst, 60-80% HMF yields were achieved in HmimCl, BdmimCl, and BmimPS in the presence of sulfuric acid or CrCl(3) in sufficient quantities.

A Discussion Paper: The Development of Professional Teacher Standards in Environmental Education
Publisher: Cambridge University Press (CUP)
Date: 2008
DOI: 10.1017/S0814062600000537
Abstract: Professional teaching associations in Australia and abroad have been developing teacher and/or teaching standards and associated professional learning and assessment models in the key discipline areas since the 1990s. In Australia, a specific intent of this approach is to capture and recognise the depth and range of accomplished educators' teaching. Despite the increasing work in this area, there has been a dearth of discussion about teacher standards in environmental education and no previous attempt to research and/or develop professional teacher standards for environmental education in Australia. This paper discusses the history of teacher standards in Australia, and considers the implications for the development of teacher standards in environmental education. In doing so, we present a research-practice model that is currently being piloted in Victoria for developing accomplished professional teacher standards and learning in environmental education with and for accomplished Australian primary and secondary teachers.

Hollow Cu2O@CoMn2O4 Nanoreactors for Electrochemical NO Reduction to NH3: Elucidating the Void‐Confinement Effects on Intermediates
Publisher: Wiley
Date: 07-08-2022
Abstract: Hollow nanoreactors show great potential in catalysis due to the void‐confinement effect. Yet few studies have investigated the void‐confinement effect of hollow nanoreactors on intermediates. Herein, electrochemical NO reduction to NH 3 (ENOR) is used as a probe reaction to study the void‐confinement effect of hollow Cu 2 O@CoMn 2 O 4 nanoreactors on intermediates. Combined with the results of catalytic activity, H 2 ‐treated in situ diffusion Fourier transform infrared spectroscopy and the finite‐element method simulation confirm that the void‐confinement effect on the intermediate is the main reason for enhanced ENOR efficiency. Additionally, theoretical calculations also show that the Cu sites of Cu 2 O@CoMn 2 O 4 nanoreactors are favorable for the formation of *NOH intermediates. This work not only gives an insight into void‐confinement effect of hollow nanoreactors on intermediates but also provides a valuable strategy for improving ENOR.

Abstract: The parameters, including ultrasonic frequency, still versus stirring, biomass particle size and biomass loading were concurrently investigated for the ultrasonic treatment of wheat straw. Experiments were conducted at three different frequencies 40, 376, and 995 kHz using three different solid to liquid ratios, 1/50, 1/20, and 1/15(g/ml), with and without mechanical stirring. Additional treatments in different particle size ranges, 0-0.5, 0.5-1, and 1-2mm were performed at the solid to liquid ratio of 1/20(g/ml). Fractionation was improved at 40 and 995 kHz via different mechanisms. Delignification was favored at the ultrasonic treatment frequency of 40 kHz, biomass loading 1/20(g/ml) with stirring and particle size range of 0.5-1mm. However at 995 kHz carbohydrate solubilization was favored, especially in the particle size range of <0.5mm. The treatment efficacies highlighted the use of ultrasound for physical and chemical effects at different frequencies.

Effect of biochar addition on hydrogen and methane production in two-phase anaerobic digestion of aqueous carbohydrates food waste
Publisher: Elsevier BV
Date: 11-2016
DOI: 10.1016/J.BIORTECH.2016.07.089
Abstract: Effect of biochar addition on hydrogen and methane production in two-phase anaerobic digestion of aqueous carbohydrates was studied using bench-scale bioreactors. The cultures with biochar additions were placed in 100ml reactors and incubated at 35°C and pH 5 for hydrogen production. The residual cultures were then used for methane production, incubated at 35°C and pH 7. Daily yields of hydrogen and methane and weekly yield of volatile fatty acids (VFA) were measured. The hydrogen and methane production potentials, rate and lag phases of the two phases were analysed using the Gompertz model. The results showed that biochar addition increased the maximum production rates of hydrogen by 32.5% and methane 41.6%, improved hydrogen yield by 31.0% and methane 10.0%, and shortened the lag phases in the two phases by 36.0% and 41.0%, respectively. Biochar addition also enhanced VFA generation during hydrogen production and VFA degradation in methane production.

DOI: 10.1016/J.WASMAN.2021.10.027
Abstract: To promote the use of recycled waste materials as an industrial feedstock, this study examined the preparation of carbon black (CB) by partial oxidation of a spent tyre pyrolysis oil using a drop tube furnace. The effect of reaction temperature, the residence time of gas in the reactor and inlet gas oxygen concentration on the yield and properties of the CB were evaluated. The surface chemistry, chemical composition, morphological and thermal properties of the CB s les were characterised using XPS, EA, TEM, BET, and TGA, respectively. The CB yield increased with increasing reaction temperature but decreased as the residence time or oxygen concentration increases. The CB primarily consisted of C (90.5-98.6%) and O (0.9-7.4%), with small traces of S (<1%), Si (<1%) and H (<2%). Hydroxyl, carbonyl, and carboxyl are the key functional groups found on the CB surface, with the hydroxyl groups being dominant. The CB were highly graphitic with a lattice spacing in the range of 0.338-0.350 nm and had BET surface areas of 4-22 m
A phenomenological investigation into the opposing effects of fluid flow on sonochemical activity at different frequency and power settings. 2. Fluid circulation at high frequencies
Publisher: Elsevier BV
Date: 03-2014
DOI: 10.1016/J.ULTSONCH.2013.09.011
Abstract: Sonochemical activity is dependent on flow patterns within the reactor and either no affect or a decrease in activity was observed at 376, 995, and 1179 kHz from overhead stirring. The interaction of fluid flow with ultrasound was further investigated in this study with circulatory flow. The effect of fluid circulation on radical production was investigated at two circulation speeds, with and without surface stabilisation. The sonochemical activity was determined by the yield of hydrogen peroxide, measured by iodide dosimetry. The sonochemically active region was pictured using sonochemiluminescence imaging and the flow fields were visualised with dyed flow videos. At 376 and 995 kHz, an increase in sonochemical activity was observed with the slower flow rate however at 1179 kHz, the sonochemical activity was either not affected or decreased. The observed changes in sonochemical activity were attributed to an increase in asymmetry of the bubble collapse brought about by fluid motion.

Socially disadvantaged women's views of barriers to feeling safe to engage in decision-making in maternity care
Publisher: Elsevier BV
Date: 06-2014
DOI: 10.1016/J.WOMBI.2013.11.003
Abstract: Although midwifery literature suggests that woman-centred care can improve the birthing experiences of women and birth outcomes for women and babies, recent research has identified challenges in supporting socially disadvantaged women to engage in decision-making regarding care options in order to attain a sense of control within their maternity care encounters. The objective of this paper is to provide an understanding of the issues that affect the socially disadvantaged woman's ability to actively engage in decision-making processes relevant to her care. The qualitative approach known as Interpretative Phenomenological Analysis was used to gain an understanding of maternity care encounters as experienced by each of the following cohorts: socially disadvantaged women, registered midwives and student midwives. This paper focuses specifically on data from participating socially disadvantaged women that relate to the elements of woman-centred care-choice and control and their understandings of capacity to engage in their maternity care encounters. Socially disadvantaged women participants did not feel safe to engage in discussions regarding choice or to seek control within their maternity care encounters. Situations such as inadequate contextualised information, perceived risks in not conforming to routine procedures, and the actions and reactions of midwives when these women did seek choice or control resulted in a silent compliance. This response was interpreted as a consequence of women's decisions to accept responsibility for their baby's wellbeing by delegating health care decision-making to the health care professional. This research found that socially disadvantaged women want to engage in their care. However without adequate information and facilitation of choice by midwives, they believe they are outsiders to the maternity care culture and decision-making processes. Consequently, they delegate responsibility for maternity care choices to those who do belong midwives. These findings suggest that midwives need to better communicate a valuing of the woman's participation in decision-making processes and to work with women so they do have a sense of belonging within the maternity care environment. Midwives need to ensure that socially disadvantaged women do feel safe about having a voice regarding their choices and find ways to give them a sense of control within their maternity care encounters.

Abstract: The interactions between coal gangue and pine sawdust during the combustion process were studied using thermogravimetric analysis. The effect of the blending ratio, oxygen concentration and heating rate on the weight loss (TG) and differential thermogravimetric (TGA) profiles was examined. The TG and DTG curves of the blends were not additives of those of the in idual materials, suggesting that interactions between coal gangue and pine sawdust had occurred during the combustion, especially in the temperature range of 400-600°C. Kinetic analysis confirmed that the combustion of coal gangue, pine sawdust and their blends was chemical reaction controlled. Further analysis revealed that the interactions between coal gangue and pine sawdust were primarily due to thermal effects rather than structural changes, with the thermal inertia of coal gangue dominating over the behaviour of the blends. The interactions decreased with decreasing the coal gangue ratio in the blend, oxygen concentration and heating rate.

Copper and zinc adsorption by softwood and hardwood biochars under elevated sulphate-induced salinity and acidic pH conditions
Publisher: Elsevier BV
Date: 2015
DOI: 10.1016/J.CHEMOSPHERE.2015.06.079
Abstract: Biochar adsorption may lower concentrations of soluble metals in pore water of sulphidic Cu/Pb-Zn mine tailings. Unlike soil, high levels of salinity and soluble cations are present in tailing pore water, which may affect biochar adsorption of metals from solution. In the present study, removal of soluble copper (Cu) and zinc (Zn) ions by soft- (pine) and hard-wood (jarrah) biochars pyrolysed at high temperature (about 700 °C) was evaluated under typical ranges of pH and salinity conditions resembling those in pore water of sulphidic tailings, prior to their direct application into the tailings. Surface alkalinity, cation exchange capacity, and negative surface charge of biochars affected Cu and Zn adsorption capacities. Quantitative comparisons were provided by fitting the adsorption equilibrium data with either the homogeneous or heterogeneous surface adsorption models (i.e. Langmuir and Freundlich, respectively). Accordingly, the jarrah biochar showed higher Cu and Zn adsorption capacity (Qmax=4.39 and 2.31 mg/g, respectively) than the softwood pine biochar (Qmax=1.47 and 1.00 mg/g). Copper and Zn adsorption by the biochars was favoured by high pH conditions under which they carried more negative charges and Cu and Zn ions were predicted undergoing hydrolysis and polymerization. Within the tested range, salinity had relatively weak effects on the adsorption, which perhaps influenced the surface charge and induced competition for negative charged sites between Na(+) and exchangeable Ca(2+) and/or heavy metal ions. Large amounts of waste wood/timber at many mine sites present a cost-effective opportunity to produce biochars for remediation of sulphidic tailings and seepage water.

Publisher: Elsevier BV

DOI: 10.1016/J.ULTSONCH.2013.07.002
Abstract: The effect of flow in an ultrasonic reactor is an important consideration for practical applications and for the scale-up of ultrasonic processing. Previous literature on the influence of flow on sonochemical activity has reported conflicting results. Therefore, this work examined the effect of overhead stirring at four different frequencies, 40, 376, 995 and 1179 kHz, in two different reactor configurations. Comparable power settings were utilised to elucidate the underlying mechanisms of interactions between the flow and sonochemical activity. The sonochemical activity was determined by the yield of hydrogen peroxide, measured by iodide dosimetry, and the active region was visualised with sonochemiluminescence imaging. The overhead stirring in the low frequency reactor altered the yield of hydrogen peroxide so it produced the maximum yield out of the four frequencies. The increase in hydrogen peroxide yield was attributed to a reduction in coalescence at 40 kHz. However at the higher frequencies, coalescence was not found to be the main reason behind the observed reductions in sonochemical yield. Rather the prevention of wave propagation and the reduction of the standing wave portion of the field were considered.

First identification of primary nanoparticles in the aggregation of HMF
Publisher: Springer Science and Business Media LLC
Date: 05-01-2012
Abstract: 5-Hydroxymethylfurfural [HMF] is an important intermediate compound for fine chemicals. It is often obtained via hydrothermal treatment of biomass-derived carbohydrates, such as fructose, glucose and sucrose. This study investigates the formation of carbonaceous spheres from HMF created by dehydration of fructose under hydrothermal conditions. The carbonaceous spheres, ranging between 0.4 and 10 μm in diameter, have granulated morphologies both on the surface and in the interior. The residual solution is found to contain a massive number of primary nanoparticles. The chemical structure of the carbonaceous spheres was characterised by means of FTIR and NMR spectroscopies. Based on these observations, a mechanism involving the formation and aggregation of the nanoparticles is proposed. This mechanism differs considerably from the conventional understanding in the open literature.

DOI: 10.1007/S10653-016-9873-6
Abstract: A wide range of waste biomass/waste wood feedstocks abundantly available at mine sites provide the opportunity to produce biochars for cost-effective improvement of mine tailings and contaminated land at metal mines. In the present study, soft- and hardwood biochars derived from pine and jarrah woods at high temperature (700 °C) were characterized for their physiochemical properties including chemical components, electrical conductivity, pH, zeta potential, cation-exchange capacity (CEC), alkalinity, BET surface area and surface morphology. Evaluating and comparing these characteristics with available data from the literature have affirmed the strong dictation of precursor type on the physiochemical properties of the biochars. The pine and jarrah wood feedstocks are mainly different in their proportions of cellulose, hemicellulose and lignin, resulting in biochars with heterogeneous physiochemical properties. The hardwood jarrah biochar exhibits much higher microporosity, alkalinity and electrostatic capacity than the softwood pine. Correlation analysis and principal component analysis also show a good correlation between CEC-BET-alkalinity, and alkalinity-ash content. These comprehensive characterization and analysis results on biochars' properties from feedstocks of hardwood (from forest land clearance at mine construction) and waste pine wood (from mining operations) will provide a good guide for tailoring biochar functionalities for remediating metal mine tailings. The relatively inert high-temperature biochars can be stored for a long term at mine closure after decades of operations.

Abstract: Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are highly recalcitrant anthropogenic chemicals that are ubiquitously present in the environment and are harmful to humans. Typical water and wastewater treatment processes (coagulation, flocculation, sedimentation, and filtration) are proven to be largely ineffective, while adsorption with granular activated carbon (GAC) has been the chief option to capture them from aqueous sources followed by incineration. However, this process is time-consuming, and produces additional solid waste and air pollution. Treatment methods for PFOS and PFOA generally follow two routes: (1) removal from source and reduce the risk (2) degradation. Emerging technologies focusing on degradation are critically reviewed in this contribution. Various processes such as bioremediation, electrocoagulation, foam fractionation, sonolysis, photocatalysis, mechanochemical, electrochemical degradation, beams of electron and plasma have been developed and studied in the past decade to address PFAS crisis. The underlying mechanisms of these PFAS degradation methods have been categorized. Two main challenges have been identified, namely complexity in large scale operation and the release of toxic byproducts. Based on the literature survey, we have provided a strength-weakness-opportunity-threat (SWOT) analysis and quantitative rating on their efficiency, environmental impact and technology readiness.

A Preliminary Investigation into the Characterization of Asphaltenes Extracted from an Oil Sand and Two Vacuum Residues from Petroleum Refining Using Nuclear Magnetic Resonance, DEPT, and MALDI-TOF
Publisher: ASME International
Date: 06-02-2017
DOI: 10.1115/1.4035746
Abstract: This paper reports the findings of an investigation into the molecular structures and properties of three asphaltene s les, namely, an asphaltene s le extracted from Buton Oil Sand (Indonesia), and two asphaltene s les extracted from vacuum residues from Liaohe Refinery (China) and Vene Refinery (Venezuela), respectively. The average molecular structural parameters, including the average polycyclic aromatic hydrocarbon (PAH) size, average side chain length, and average molecular weight (AMW), of the three asphaltene s les were estimated using data from nuclear magnetic resonance (NMR) in combination with distortionless enhancement by polarization transfer (DEPT), and then compared against each other. The molecular weight distributions (MWDs) of the three asphaltene s les were measured using a matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The results indicated that the island molecular architecture predominated in all three asphaltenes and the average polycyclic aromatic hydrocarbon size was found to be six rings. The average molecular weight of the Buton asphaltene s le was found to be ca. 800 Da while those of the two petroleum asphaltene s les were approximately 600 Da. In comparison, the Buton asphaltene s le contained a much higher level of oxygen and sulfur, but a lower aromaticity than those of the two petroleum asphaltene s les. The use of liquid NMR in combination with DEPT was shown to provide an effective method for characterization and estimation of the molecular structures of asphaltenes, supported by MALDI-TOF mass spectra.

A preliminary assessment of the potential of using an acacia—biochar system for spent mine site rehabilitation
Publisher: Springer Science and Business Media LLC
Date: 30-08-2015
DOI: 10.1007/S11356-014-3451-1
Abstract: Mining activities result in extensive soil degradation by removing the top soil, disturbing soil structure and altering microbial communities. Rehabilitation of spent mine sites through revegetation thus requires proper soil amendments. In this study, a pot trial was conducted to investigate the effects of a jarrah biochar on the growth and nutrient status of a native legume, Acacia tetragonophylla, grown in a mixture of topsoil and mine rejects. Two biochar application rates (37 and 74 t ha(-1)) and two types of biochar, namely nutrient-enriched and non-enriched, were tested. We measured the soil pH and electrical conductivity, the carbon (C) and nitrogen (N) contents and C and N isotope composition (δ(13)C and δ(15)N) of soil and plants, the foliar phosphorus content and the growth and leaf biomass of the plants. Whilst no significant effect of biochar was observed on plant growth, biochar amendment affected soil properties and plant nutritional status. The highest rate of biochar application increased soil pH, C content and C/N ratio, and decreased soil δ(13)C. Biochar application also enhanced photosynthetic N use efficiency, as showed by the increase in foliar C/N ratio, and biological N fixation rates, as indicated by foliar δ(15)N. These positive effects were not observed when biochar was nutrient-enriched due to the associated increase in soil N. Revegetation of mine sites with acacia in combination with biochar amendment constitutes a plausible alternative to the wide use of N fertiliser through the supply of additional N to the system, even though other nutrients may be required in order to enhance plant early growth.
Effect of Biochar Addition and Temperature on Hydrogen Production From the First Phase of Two-Phase Anaerobic Digestion of Carbohydrates Food Waste
Publisher: ASME International
Date: 20-03-2018
DOI: 10.1115/1.4039318
Abstract: This paper reports an experimental study of the effect of biochar addition and temperature on hydrogen production in the first phase of the two-phase anaerobic digestion (TPAD) of carbohydrates food waste. Anaerobic digestion (AD) experiments using white bread representing carbohydrate food wastes were conducted in bench scale 100 ml reactors. The cultures with biochar addition were placed in the reactors and incubated at different temperatures (18, 35, and 52 °C) over a period of 8 days. The biochar addition ratio was varied from 0 to 18.6 g l−1. The daily volumetric hydrogen production was measured, and the cumulative yield (YH) and daily production rate (RH) of hydrogen were calculated. Both biochar addition and temperature affected hydrogen production significantly. YH and maximum RH increased as the biochar addition ratio increased from 0 to 10 g l−1 then decreased as the biochar addition ratio further increased up to 18.6 g l−1. At different temperatures, YH varied significantly, increasing from 846 ± 18 ml l−1 at 18 °C to 1475 ± 53 ml l−1 at 35 °C and dropped to 1149 ± 26 ml l−1 at 52 °C. The maximum RH also peaked at 35 °C, reaching 858 ± 57.1 ml l−1 day−1. The effect of biochar addition was more profound under mesophilic conditions. The results of this study confirmed the beneficial effect of biochar addition in hydrogen production of carbohydrate food waste in the TPAD process.

Burst mode in a cooled packed-bed dielectric barrier discharge reactor for CO2 splitting *
Publisher: IOP Publishing
Date: 20-05-2021
Abstract: The so called ‘burst mode’, a rapidly pulsed power regime for dielectric barrier discharges (DBDs) has previously been reported to greatly improve the performance of an uncooled and unpacked DBD reactor for CO 2 splitting. Here we explore the interaction between a DBD in burst mode and each of active cooling and a dielectric packing material (1.0–1.2 mm glass beads) in a coaxial, metal-dielectric DBD reactor for CO 2 splitting. The effect of burst mode on CO 2 conversion and energy efficiency under different combinations of cooling and packing were investigated and compared with those under continuous wave mode operation. The burst mode operation showed similar CO2 conversion and energy efficiency to continuous wave mode in the unpacked and uncooled configuration under the conditions investigated in this study. However, burst mode significantly outperformed continuous wave mode in the packed and uncooled configuration. When active cooling was employed, burst mode was found to provide only minor benefit or no benefit, depending on specific energy input (SEI), compared to continuous wave mode for each the packed and unpacked configurations. Maximum conversion and energy efficiency were achieved with both packing and active cooling across all SEI examined, and performance in this configuration was found to be relatively insensitive to the power delivery mode.

Rheological Properties and Ignition and Combustion Characteristics of Biochar–Algae–Water Slurry Fuels
Publisher: ASME International
Date: 14-03-2018
DOI: 10.1115/1.4039320
Abstract: This study examined the rheological properties, ignition, and combustion characteristics of biochar–algae–water (BAW) slurry fuels. A pine sawdust biochar with a median particle size (D50) of approximately 12 μm and algae Chlorella vulgaris in dry powder form with D50 of approximately 19 μm were used. The BAW slurries with a constant solid loading of 40 wt % and algae/biochar ratio varying from 0 to 0.2 by weight were prepared. The apparent viscosity was measured using a Haake VT550 cone-and-plate viscometer. The stability of the slurries was characterized using a “drop rod” method. Ignition and combustion characteristics of the slurries were studied using a suspended single-droplet technique. A single droplet of a slurry fuel with a diameter ranging from 0.5 mm to 1.5 mm was suspended on a silicon carbide fibre and burned in air at 1023 K in an electrically heated tube furnace. The ignition and combustion processes of the droplet were recorded using a CCD camera at 200 fps. The ignition delay time, burnout time, and burning rate were determined. The BAW slurries showed shear-thinning flow behavior. The slurries had higher viscosity and greater stability at higher algae proportion in the solid. The ignition and combustion process of BAW slurries followed the sequence of water evaporation, devolatilization, ignition, and combustion of the solid residue. The combustion of the residual solid was diffusion controlled under the experimental conditions and the burning rates of the BAW slurry droplets ranged from 0.15 to 0.25 mm2 s−1.
Contrasting the Pyrolysis Behavior of Selected Biomass and the Effect of Lignin
Publisher: ASME International
Date: 27-02-2018
DOI: 10.1115/1.4039321
Abstract: This study was aimed at comparing the pyrolysis behavior of several selected biomass s les, namely, pine wood, poplar wood, wheat straw, and sugarcane bagasse, with a particular attention to the effect of lignin. Raw s les were first treated using Soxhlet solvent extraction with a 2:1 (v/v) mixture of toluene/ethanol to remove wax. Lignin was then removed by soaking the dewaxed s les in a 1.0 M sodium chlorite solution at 343 K till the solids became white. Fourier transform infrared (FTIR) spectroscopy analysis was applied to characterize the surface functional groups of the s les. The morphology of the s les before and after delignification treatment was analyzed using scanning electron microscope (SEM). The pyrolysis behavior of the raw and treated biomass s les was studied using a thermogravimetric analyzer (TGA) operating in nitrogen at a constant heating rate of 10 K min−1 from room temperature to the final temperature 823 K. The FTIR and SEM results indicated that lignin can be successfully removed from the raw biomass via the chemical treatment used. As expected, the pyrolysis behavior differed significantly among the various raw biomass s les. However, the pyrolysis behavior of the delignified s les showed almost identical thermal behavior although the temperature associated with the maximum rate of pyrolysis was shifted to a lower temperature regime by ca. 50 K. This suggests that the presence of lignin significantly affected the biomass pyrolysis behavior. Thus, the pyrolysis behavior of the biomass cannot be predicted simply from the in idual components without considering their interactions.

Effect of Heat Treatment on the Combustion Characteristics of a Lignite

Date: 11-03-2019
DOI: 10.1115/1.4042823
Abstract: In this study, the ignition and combustion behavior of raw and heat-treated single particles of lignite were experimentally investigated, with a focus on the effect of heat treatment temperatures. The lignite particles were heat treated to various final temperatures (473, 623 and 773 K) in nitrogen and characterized using proximate, ultimate, and Fourier transform infrared spectroscopy (FTIR) analysis. A single lignite particle of 2 or 3 mm in diameter was suspended on a silicon carbide fiber and burned in air in a horizontal tube furnace operating at 1123 K. The ignition and combustion process of the particle was record using a color CCD camera at 25 fps. The ignition mechanism, ignition delay time, volatile flame duration, and burnout time of the single particles were examined by processing the recorded images. The proximate and ultimate analysis results indicated that the volatile matter and oxygen contents decreased, while the carbon content increased with increasing temperature of heat treatment. This trend was consistent with observations in the FTIR analysis, in which the intensity of oxygen-containing functional groups decreased with increasing the heat treatment temperature. The ignition of raw and heat treated lignite particles followed a joint hetero-homogeneous mechanism under all conditions studied. The ignition delay time, volatile flame extinction time, and the total combustion time decreased with increasing heat treatment temperature up to 623 K. A further increase in the heat treatment temperature to 773 K resulted in prolonged key ignition and combustion characteristic times.
Insight into the Mechanism of Selective Catalytic Reduction of NOx by Propene over the Cu/Ti0.7Zr0.3O2 Catalyst by Fourier Transform Infrared Spectro
Publisher: American Chemical Society (ACS)
Date: 05-04-2013
DOI: 10.1021/ES3049898
Abstract: The mechanism of selective catalytic reduction of NOx by propene (C3H6-SCR) over the Cu/Ti0.7Zr0.3O2 catalyst was studied by in situ Fourier transform infrared (FTIR) spectroscopy and density functional theory (DFT) calculations. Especially, the formation and transformation of cyanide (-CN species) during the reaction was discussed. According to FTIR results, the excellent performance of the Cu/Ti0.7Zr0.3O2 catalyst in C3H6-SCR was attributed to the coexistence of two parallel pathways to produce N2 by the isocyanate (-NCO species) and -CN species intermediates. Besides the hydrolysis of the -NCO species, the reaction between the -CN species and nitrates and/or NO2 was also a crucial pathway for the NO reduction. On the basis of the DFT calculations on the energy of possible intermediates and transition states at the B3LYP/6-311 G (d, p) level of theory, the reaction channel of -CN species in the SCR reaction was identified and the role of -CN species as a crucial intermediate to generate N2 was also confirmed from the thermodynamics view. In combination of the FTIR and DFT results, a modified mechanism with two parallel pathways to produce N2 by the reaction of -NCO and -CN species over the Cu/Ti0.7Zr0.3O2 catalyst was proposed.
