Development of a novel desalination process. The process proposed in this submission provides a simple, flexible and cost effective platform for small-scale desalination applications. The proposed process can be an integral part of a more comprehensive approach to resolve the shortage of freshwater in arid to semi-arid regions of rural Australia. This will contribute to the Federal Government's National Research Priority 1: An Environmentally Sustainable Australia, particularly the priority goal ....Development of a novel desalination process.

The Effects of Pyrolysis Conditions on Combustion and Gasification Reactivities of Biomass Chars and the Quality of Their Ash. Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass. Many of the challenges associated with the thermal conversion of biomass relate to its char characteristics. The aim of this project is to gain a fundamental understanding about the impact of reaction conditions during the pyrolyti ....The Effects of Pyrolysis Conditions on Combustion and Gasification Reactivities of Biomass Chars and the Quality of Their Ash. Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass. Many of the challenges associated with the thermal conversion of biomass relate to its char characteristics. The aim of this project is to gain a fundamental understanding about the impact of reaction conditions during the pyrolytic stage on the structural and compositional transformations of the resultant char, its combustion and gasification reactivities, and the release of inorganic matter and ash formation. This holistic and integrated approach should reveal the underlying science necessary to support existing and future biomass use.Read moreRead less
Supercritical Highly-Integrated and Modular, Continuous Solid-Catalysed Biodiesel Production from Plant and Animal Feedstocks. We propose to revolutionise biodiesel production by creating a new reactor type and associated process that allows the production of 160,000 tonnes of biodiesel a year in a supercritical reactor volume of one cubic metre after scale-up. In this project, we propose to design the appropriate catalysts and pilot plant to study our ideas which should lead to a highly effici ....Supercritical Highly-Integrated and Modular, Continuous Solid-Catalysed Biodiesel Production from Plant and Animal Feedstocks.

In this project, we propose to design the appropriate catalysts and pilot plant to study our ideas which should lead to a highly efficient and sustainable system that offers a real alternative to current mineral oil-based technologies.Read moreRead less
Measurement and Prevention of Membrane Fouling for Water Reuse in Biorefineries. The effluent streams from molasses based fermentation contain dark-coloured melanoidins (recalcitrant COD) which limit discharge options and make water recovery via membrane technology challenging. Understanding membrane fouling to a level where its behaviour can be reliably predicted is a vital step in gaining widespread acceptance of this technology. Advances made here have a built-in multiplier effect, as insight ....Measurement and Prevention of Membrane Fouling for Water Reuse in Biorefineries. The effluent streams from molasses based fermentation contain dark-coloured melanoidins (recalcitrant COD) which limit discharge options and make water recovery via membrane technology challenging. Understanding membrane fouling to a level where its behaviour can be reliably predicted is a vital step in gaining widespread acceptance of this technology. Advances made here have a built-in multiplier effect, as insights from yeast production (core business for our industrial partner A B Mauri) can be readily applied to large-scale fermentation producing fuel alcohol from molasses as well as the emerging use of lignocellulosics. This project will contribute significantly to sustainability by reducing industrial water consumption.Read moreRead less
Combustion Characteristics of Biomass Chars in Pressurised Circulating Fluidised Bed Reactors. The development of new, cleaner methods of electricity generation, such as biomass-based integrated gasification combined-cycles and hybrid-cycle pressurised fluidised-bed combustion, have highlighted the need for a greater understanding of the combustion characteristics of biomass chars at high pressures and temperatures. The aim of this project is to gain a clearer understanding of the underlying mec ....Combustion Characteristics of Biomass Chars in Pressurised Circulating Fluidised Bed Reactors. The development of new, cleaner methods of electricity generation, such as biomass-based integrated gasification combined-cycles and hybrid-cycle pressurised fluidised-bed combustion, have highlighted the need for a greater understanding of the combustion characteristics of biomass chars at high pressures and temperatures. The aim of this project is to gain a clearer understanding of the underlying mechanisms that control the combustion of biomass chars in pressurised circulating fluidised-bed (PCFB) reactors. The fundamental knowledge gained in this project will have immediate practical applications as modern PCFB reactors are considered to be the most suitable systems for the combustion of biomass char particles.Read moreRead less
Designing integrated photocatalytic systems for simultaneous clean energy generation and water remediation. 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.

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
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
Optimisation and Control of Bagasse Handling System in a Sugar Mill. Bagasse, the fibre residue from sugar cane, is used as fuel in suspension fired boilers for energy production for the sugar milling process. The use of bagasse as a fuel is currently gaining more prominence as the sugar industry looks to co-generation joint ventures with traditional electricity supply and generation authorities.

Bagasse, the fibre residue from sugar cane, is used as fuel in suspension fired boilers for energy production for the sugar milling process. The use of bagasse as a fuel is currently gaining more prominence as the sugar industry looks to co-generation joint ventures with traditional electricity supply and generation authorities. This project is aimed at applying optimisation and control techniques to bagasse handling system in a CSR sugar mill so that the fibre residue from sugar cane can be used to gain maximum efficiency in generating energy supplies in the sugar mill. If the project succeeds, other sugar mills from CSR would implement the advanced control system.Read moreRead less
