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
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). This work will minimise emissions from such industries, as well as reduce lubricant oil usage - thereby maximising waste oil recovery and reuse (approx 5 ....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). 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

This research will contribute to a more environmentally sustainable Australia because it will promote the use of natural gas as a fuel supply which produces significantly fewer greenhouse gases than oil or coal. This project will improve the ability of engineers to reliably simulate LNG production plants as well as test new processes and technologies with the potential to increase efficiency or revenue. Consequently, the level of over-engineering and, thus, the capital and operational costs of such plants will decrease. This in turn will promote the development of Australian gas reserves, particularly for those fields currently on the margins of economic viability.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

This research will contribute to a more environmentally sustainable Australia because it will promote the use of natural gas as a fuel supply which produces significantly less greenhouse gases than oil or coal. It will contribute to the harnessing of some of Australia's largest gas reserves, like the Gorgon field, which are contaminated with large amounts of CO2 and are not yet economically viable. The removal of N2 from natural gas will reduce the cost of producing LNG which is the only method Australia can use to access global gas markets. The new adsorbent materials developed for this work may enhance other research programmes attempting to capture and sequester CO2 from industrial flue gases.Read moreRead less
