Engineering two dimensional polymers for membrane-based chemical separation. This project aims to develop novel two-dimensional polymers with precisely controlled pore-sizes for preparing membrane materials which can efficiently separate these gaseous chemicals at ambient temperatures. Key industrial chemical mixtures with similar size and boiling points are difficult to separate by conventional distillation methods. Currently, purification of olefins alone accounts for 0.3% of global energy use ....Engineering two dimensional polymers for membrane-based chemical separation. This project aims to develop novel two-dimensional polymers with precisely controlled pore-sizes for preparing membrane materials which can efficiently separate these gaseous chemicals at ambient temperatures. Key industrial chemical mixtures with similar size and boiling points are difficult to separate by conventional distillation methods. Currently, purification of olefins alone accounts for 0.3% of global energy use. The expected outcomes of the project will have a huge impact on industrial purification processing by providing a disruptive membrane technology, and will significantly reduce energy consumption and open up new routes for resources.Read moreRead less
Homogeneous Combustion Catalysts for Efficiency Improvements and Emission Reduction in Diesel Engines. Australia currently consumes about 25 billion litres of diesel annually through the mining industry, road transportation and electricity generation for remote communities which presentins a significant cost and carbon footprint. A small reduction of say 2.5% in diesel consumption nationwide by improving engine performance and energy efficiency can result in more than $0.5 billion in savings and ....Homogeneous Combustion Catalysts for Efficiency Improvements and Emission Reduction in Diesel Engines. Australia currently consumes about 25 billion litres of diesel annually through the mining industry, road transportation and electricity generation for remote communities which presentins a significant cost and carbon footprint. A small reduction of say 2.5% in diesel consumption nationwide by improving engine performance and energy efficiency can result in more than $0.5 billion in savings and a reduction of 1.75 million tonnes in greenhouse gas emission annually. The homogeneous combustion catalysts, to be developed in this research for direct doping into diesel supply system, will help realise these objectives and contribute to the development of an environmentally sustainable Australia.Read moreRead less
Electrocoagulation as a low-cost option for the continuous treatment of highly polluted wastewater. Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users.

Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users. Detailed scoping work in 2005 has identified electrocoagulation as a technically simple and economically viable option for this industry sector. Our industry partner is part of a global multi-national corporation within which successful wastewater treatment technology will be rapidly exploited and exported. Read moreRead less
Process studies for photocatalytic rejuvenation of spent industrial Bayer liquor. A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.
Electrochemical conversion of carbon dioxide to formic acid. This project aims to develop economical and scalable carbon dioxide electrochemical technologies to convert carbon dioxide in blast furnace flue gas to formic acid as a value-added product in steel-making plants. The project expects to develop new electrochemical catalysts, to optimise the structure of electrodes and ultimately improve carbon dioxide conversion efficiency and reaction selectivity towards formic acid.

Reactivity of Carbon-Carbon Composites. This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temper ....Reactivity of Carbon-Carbon Composites. This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temperatures on the relationship between anode microstructure and reactivity in oxygen as well as carbon dioxide will be investigated, and optimum process conditions determined for minimum reactive carbon loss during smelting.Read moreRead less
Increasing the operational lifetime and optimising the design of crankcase oil-mist filters. Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining).

Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining). This work will minimise emissions from such industries, as well as reduce lubricant oil usage - thereby maximising waste oil recovery and reuse (approx 5500 tonnes p.a.). Oil mists can be regarded as volatile organic compounds (VOCs) for the purposes of CO2 equivalent emissions, so therefore, the efficient capture of oil mists will reduce carbon emissions from the above industries in Australia.Read moreRead less
Micromechanical analysis of size segregation and its prediction in granular free-surface flows. Industries often suffer from size segregation in the handling and processing of granular materials, leading to significant economic consequences. This project aims to develop a fundamental understanding of size segregation and prediction models, enabling industries to eliminate, minimise, or manage the effects to an acceptable level.
Development of ultrastable high flux hydrophobic pervaporation membranes for organic separations. Perfluorinated glassy polymers (Teflons AF) as membrane materials are endowed with unique fluxes and excellent stability when in contact with various liquid organic mixtures. However, they have never been explored as membrane materials for pervaporation.

However, they have never been explored as membrane materials for pervaporation. The aims of this project are therefore to evaluate the applicability of composite membranes based on amorphous Teflons AF to the separation of organic mixtures and the removal of organic pollutants from water.
