System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation including flow visualization by PIV to systematically investigate the effect of channel geometry and flow on deposit formation. The outcomes of the project will result in a better understanding and formulating of the effect of geometry on deposition of colloidal particles and ionic species on the surfaces. The results contribute not only towards the mitigation processes for unwanted deposition; it also advances the knowledge in coating applications.Read moreRead less

The novel reaction system and research methodologies proposed in this proposal will certainly enhance Australia's science and technology capability and international competitiveness, in the area of reaction engineering. Also of the national benefit is the successful training of a postgraduate at PhD level who will no doubt add to future scientific research workforce.Read moreRead less
Production of diesel from the catalytic pyrolysis of waste plastics. Large amounts of waste plastics go to landfill daily. Landfill simply buries our wastes for future generations and can contribute to the contamination of ground water.

Large amounts of waste plastics go to landfill daily. Landfill simply buries our wastes for future generations and can contribute to the contamination of ground water. This project aims to develop an advanced pyrolysis technology to produce transport diesel from waste plastics. This technology is an economically attractive and environmentally friendly way for the disposal of waste plastics without any environmental problems associated with the landfill or direct incineration of waste plastics. As this technology is based on advances in Australian research and development, exporting this to other countries will further enhance its economic and social benefits to Australia.Read moreRead less
A Comprehensive Kinetic Model for Sulfur Reactions in Combustion, Gasification, and Chemical Processing. Sulfur chemistry in high temperature processes is poorly understood, leading to uncertainties in the design of these processes and in the control of their emissions. In particular, new approaches to lowering greenhouse emissions which depend on the combustion and gasification of coal, biomass, or refuse-derived fuel, such as integrated gasification combined cycle processes, are especially aff ....A Comprehensive Kinetic Model for Sulfur Reactions in Combustion, Gasification, and Chemical Processing. Sulfur chemistry in high temperature processes is poorly understood, leading to uncertainties in the design of these processes and in the control of their emissions. In particular, new approaches to lowering greenhouse emissions which depend on the combustion and gasification of coal, biomass, or refuse-derived fuel, such as integrated gasification combined cycle processes, are especially affected by these uncertainties. This project seeks to combine experimental measurements and quantum chemical modelling to produce a detailed mechanistic model for the reactions of sulfur in high-temperature systems. Such a model will provide designers with a tool to optimise these complex interacting systems.Read moreRead less
Nano- and micro-scale engineering of MoS2-based catalyst for conversion of syngas to ethanol. Domestic production of ethanol to provide a 10% blend in petrol (E10) can be achieved from waste methane gas that Australia currently vents or flares to atmosphere. This project aims to develop a conversion process for making ethanol from syngas (the product of coal or methane gasification). Small scale, modularised plants would make ethanol locally to the methane emission source. The benefits of local ....Nano- and micro-scale engineering of MoS2-based catalyst for conversion of syngas to ethanol. Domestic production of ethanol to provide a 10% blend in petrol (E10) can be achieved from waste methane gas that Australia currently vents or flares to atmosphere. This project aims to develop a conversion process for making ethanol from syngas (the product of coal or methane gasification). Small scale, modularised plants would make ethanol locally to the methane emission source. The benefits of local E10 production would be a reduction in the oil trade deficit of $1 billion per year, $500 million per year in lower carbon imposts to industry and government, 25 million tonnes per year of reduced CO2e release to atmosphere and significantly improved urban air through reduced emissions from car transport, with attendant human health benefits.Read moreRead less

The facility will be used by the collaborating universities to investigate adsorption and interface properties with great precision, and to develop new and improved technologies for coal and mineral processing, saline water utilisation, water desalination, energy production and environment protection. In particular, the project will investigate innovative ways of using ion-interface interactions in saline water for cleaning coal and recovering value minerals by flotation, and for improving dissolved air flotation used in water treatment and desalination to produce drinking water. The project will further investigate novel ways of capturing CO2, storing natural gases and hydrogen, and tailoring nutrient nano-crystals for foliar delivery.Read moreRead less

The proposal addresses the core issues of energy and water, two highly critical resources in Australia as well as worldwide. Utilising our geographically-abundant solar energy and through designing novel photocatalytic systems, the proposed research provides an ultimately clean solution by efficiently harnessing and converting the solar energy to hydrogen while remediating wastewater. Given the high intensity and consistent solar output in Australia, such technology provides an almost ideal and sustainable outcome in terms of clean energy and water supply. Success in this area will place Australian researchers at the forefront of practical and functional photocatalytic technologiesRead moreRead less
Improvements and Optimisation of Water Electrolysis for Hydroxy Gas Production for Metal Cutting Applications. The current technique for metal cutting mainly uses oxygen-acetylene flames, which means for the large number of Australian remote communities oxygen and acetylene bottles have to be transported from major cities. This incurs significant transport costs and associated environmental emissions and presents major safety concerns. Hydroxy flames using electrolysis of water can alleviate the ....Improvements and Optimisation of Water Electrolysis for Hydroxy Gas Production for Metal Cutting Applications. The current technique for metal cutting mainly uses oxygen-acetylene flames, which means for the large number of Australian remote communities oxygen and acetylene bottles have to be transported from major cities. This incurs significant transport costs and associated environmental emissions and presents major safety concerns. Hydroxy flames using electrolysis of water can alleviate these problems and, by utilising renewable electricity, the new technology to be developed in this research will transform tens of thousands of Australian metal workshops to be more environmentally friendly, safer and more cost-effective, thus contributing to the development of an environmentally sustainable Australia.

Establishing the pathways of biomass decomposition in hot compressed water. Australia has significant under-developed biomass and brown coal resources which could feasibly be used to produce transport fuels and industrial chemicals. The successful conversion of these resources will offset the rising cost of petrochemicals, reduce oil import dependency, and in the longer term, address some of the challenges of climate change. We will directly address this problem by investigating the mechanism of ....Establishing the pathways of biomass decomposition in hot compressed water. Australia has significant under-developed biomass and brown coal resources which could feasibly be used to produce transport fuels and industrial chemicals. The successful conversion of these resources will offset the rising cost of petrochemicals, reduce oil import dependency, and in the longer term, address some of the challenges of climate change. We will directly address this problem by investigating the mechanism of conversion of biomass and brown coal resources to targeted chemical products, at laboratory and pilot scale, as a precursor to the development of a commercial biorefinery.Read moreRead less
