A Fundamental Study on Redox Behaviour of Oxygen Carriers in Chemical Looping Combustion. Our goal here is to acquire fundamental knowledge about the redox behaviour of metal oxide oxygen carriers which, arguably, underpins the feasibility of the Chemical Looping Combustion (CLC) concept. Although the proposed work is fundamental and will contribute to the advancement of knowledge, the results will have immediate practical applications in power generation industry at both national and internatio ....A Fundamental Study on Redox Behaviour of Oxygen Carriers in Chemical Looping Combustion. Our goal here is to acquire fundamental knowledge about the redox behaviour of metal oxide oxygen carriers which, arguably, underpins the feasibility of the Chemical Looping Combustion (CLC) concept. Although the proposed work is fundamental and will contribute to the advancement of knowledge, the results will have immediate practical applications in power generation industry at both national and international levels. This should significantly contribute to the Australian Government's efforts in producing world class solutions for abatement of greenhouse emissions (Research Priority 1: An Environmentally Sustainable Australia, Priority Goal 1.4 - Reducing and capturing emissions in transport and energy generation).Read moreRead less
Selective generation of hydrogen from biomass and waste fuels. Biomass fuels account for 14% of global energy supply. This is likely to increase in future as the population increases, energy demand rises, cheap oil and coal reserves are depleted, and the effects of global warming become more readily visible. In Australia the development of a sustainable hydrogen economy is a national priority. The hydrogen economy could bring about improved energy security, substantially reduced greenhouse gas e ....Selective generation of hydrogen from biomass and waste fuels. Biomass fuels account for 14% of global energy supply. This is likely to increase in future as the population increases, energy demand rises, cheap oil and coal reserves are depleted, and the effects of global warming become more readily visible. In Australia the development of a sustainable hydrogen economy is a national priority. The hydrogen economy could bring about improved energy security, substantially reduced greenhouse gas emissions, improved energy efficiency and improved air quality. This proposal directly addresses this challenge by investigating the science underpinning a large-scale sustainable hydrogen synthesis process using biomass and waste fuels. 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

Summary
Facility for Analysis of Thermal Decomposition of Solid Materials at High Pressures. This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia. The facility will consist of a high-pressure thermal gravimetric analyser (TGA) able to operate at up to 5 MPa, which will be coupled to a mass spectrometer (MS) for identification and quan ....Facility for Analysis of Thermal Decomposition of Solid Materials at High Pressures. This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia. The facility will consist of a high-pressure thermal gravimetric analyser (TGA) able to operate at up to 5 MPa, which will be coupled to a mass spectrometer (MS) for identification and quantification of gaseous reaction products. The facility constitutes unique and significant national research infrastructure for the simultaneous acquisition of mass loss kinetic measurements together with characterisation and quantification of emission rates of gaseous fragments generated in the reaction. As a major outcome, the facility will provide a means for consistent investigation of kinetics of elemental reactions occurring in solids, or on solid surfaces during pyrolysis and gasification processes at high pressure.Read moreRead less
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
