Frictional and viscous effects during transport in nanopores. Gas mixtures exposed to materials containing molecular sized pores (nanopores) are adsorbed, forming states of matter not existing in the bulk. Differential forces acting on the components of mixtures promote industrially and environmentally important separations. However, transport of confined fluids has been poorly understood. Recently we have made progress using computer simulation, and have proposed a highly successful theory. ....Frictional and viscous effects during transport in nanopores. Gas mixtures exposed to materials containing molecular sized pores (nanopores) are adsorbed, forming states of matter not existing in the bulk. Differential forces acting on the components of mixtures promote industrially and environmentally important separations. However, transport of confined fluids has been poorly understood. Recently we have made progress using computer simulation, and have proposed a highly successful theory. These investigations have revealed the crucial role of scattering from the surface atoms of the confining solid. Theoretical investigation of single spherical species has been initiated, and extension to other species and to mixtures is now envisaged.Read moreRead less
Multicomponent Transport in Nanopores. Good understanding of transport mechanisms in nanopores is crucial to the successful application of numerous recently developed novel templated microporous and mesoporous materials. This project seeks to extend a new theory developed by the applicants for single component transport in cylindrical mesopores, to cylindrical micropores as well as to multicomponent adsorbates, in conjunction with experiments using microporous and mesoporous materials such as M ....Multicomponent Transport in Nanopores. Good understanding of transport mechanisms in nanopores is crucial to the successful application of numerous recently developed novel templated microporous and mesoporous materials. This project seeks to extend a new theory developed by the applicants for single component transport in cylindrical mesopores, to cylindrical micropores as well as to multicomponent adsorbates, in conjunction with experiments using microporous and mesoporous materials such as MCM-41, VPI-5 and AlPO4-5. The outcome will be a powerful new theory for a priori prediction of transport coefficients for multicomponent fluids in nanopores based on molecular level information alone, thereby overcoming the empiricism in existing models.Read moreRead less
Optimisation of Dual Fuel Compression Ignition (Diesel) Engines With Respect to Engine Performance and Pollutant Emissions. A successful dual-fuel compression ignition (diesel) engine technology utilizing renewable alcohol fuels will provide a commercially attractive, immediate solution to the global fuel challenges of security and cost of oil supply, greenhouse gas emissions, and air quality . This project provides both the rigorous laboratory and field testing required to develop, test, optim ....Optimisation of Dual Fuel Compression Ignition (Diesel) Engines With Respect to Engine Performance and Pollutant Emissions. A successful dual-fuel compression ignition (diesel) engine technology utilizing renewable alcohol fuels will provide a commercially attractive, immediate solution to the global fuel challenges of security and cost of oil supply, greenhouse gas emissions, and air quality . This project provides both the rigorous laboratory and field testing required to develop, test, optimize and validate both engine performance and pollution emissions. This ethanol dual fuel approach has the potential to reduce Australia's dependence on imported fuels, support the development of regional agriculture and employment through the expansion of the biofuels industry and enhance the environmental performance of transport and stationary engines.Read moreRead less
Effectiveness of deep natural clay, compacted clay and geomembranes in limiting seepage from coal seam gas production water evaporation ponds. Australia's coal seam gas reserves exceed those of the Moomba and Bass Strait gas fields combined. Queensland's coal seam gas production already accounts for more than 50% of the state's natural gas supply, and continues to grow rapidly. The production of coal seam gas will escalate in coming years, particularly to provide a clean fuel for electricity g ....Effectiveness of deep natural clay, compacted clay and geomembranes in limiting seepage from coal seam gas production water evaporation ponds. Australia's coal seam gas reserves exceed those of the Moomba and Bass Strait gas fields combined. Queensland's coal seam gas production already accounts for more than 50% of the state's natural gas supply, and continues to grow rapidly. The production of coal seam gas will escalate in coming years, particularly to provide a clean fuel for electricity generation and feed stock for liquefied natural gas to supply rapidly growing markets in Asia. As gas production increases, so too does the generation of saline water. This research will ensure that the evaporation of the saline water does not impact the underlying Great Artesian Basin, so that coal seam gas production may continue and grow.Read moreRead less

Particulate Science and Technology (PST) is a rapidly developing interdisciplinary research field concerned with particle-related phenomena at different time and length scales and represents a very significant research and development effort in Australia for many years. This network is formed by linking the world-recognized research centres/groups with different expertise. Its aim is to provide greater collaboration among the Australian and overseas researchers and enhance the scale and focus of particulate research. It will help develop and maintain Australia's leading position in PST, generating massive research outcomes and training that can lead to improvement in resource, energy, process and allied industries.Read moreRead less
Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of thi ....Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of this proposal is to develop trickle filters to treat the sour water. The biofilms that develop in trickle filters are ideal for supporting slow growing microbial species. Research is needed to transfer native microorganisms in the oil shale desposit to the durable gravels that will be used in the filter.Read moreRead less
Understanding salt dynamics to facilitate water reuse on coal mine sites. Coal mining in Central Queensland occurs in a water scarce region. Coal is a very high value product per unit of water consumed. The industry wishes to expand and to meet current water needs partially by increasing water reuse on site. Difficulties associated with managing salt, in its various forms across a mine site, limit this. This project will produce operational guidelines to overcome these limitations allowing th ....Understanding salt dynamics to facilitate water reuse on coal mine sites.

The industry wishes to expand and to meet current water needs partially by increasing water reuse on site. Difficulties associated with managing salt, in its various forms across a mine site, limit this. This project will produce operational guidelines to overcome these limitations allowing the coal industry to decrease its water footprint by increasing and properly managing water reuse.Read moreRead less
