Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramifi ....Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramification. In contrast, our proposed technique avoids the production of greenhouse gases and, instead, engenders high value added graphitized carbon as a by-product. Given the relative stability and value of graphitized carbon, our catalytic cracking process provides another option to geosequestration.Read moreRead less
Development of a Novel Flue Gas Desulphurization Technology for Alumina Refineries. This project aims to develop a novel technology of flue gas desulphurization for alumina industry. The successful completion of this project will provide a practical solution to the SOx emission problem in alumina refineries. Specifically, we aim to make use of the waste causticiser sludge discharged during the causticisation of the liquor streams and the used filter aid after the polishing filtration of the ref ....Development of a Novel Flue Gas Desulphurization Technology for Alumina Refineries. This project aims to develop a novel technology of flue gas desulphurization for alumina industry. The successful completion of this project will provide a practical solution to the SOx emission problem in alumina refineries. Specifically, we aim to make use of the waste causticiser sludge discharged during the causticisation of the liquor streams and the used filter aid after the polishing filtration of the refinery pregnant liquors as reagent to remove SOx emitted by the power house and the alumina calciners. We also aim to recover some alumina during the process of flue gas desulphurization thus further reducing the cost of air pollution control.Read moreRead less
Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance ....Development and Modellling of Advanced Coagulation and Oxidation Processes.

It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance for removing NOM, and possess antimicrobial properties (ii) developing a new energy efficient photocatalysis technology.The proposed research will expand the knowledge base in this area and increase Australia’s international profile as a global leader in developing cutting-edge cost effective water resource technologies.Read moreRead less
Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but the ....Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but these attempts have been of limited success. The present research involves a completely new approach to the problem, which is based on the method used in the heat treatment of sapphire to improve its colour. This approach uses a phenomenon involving the modification of the optical properties to improve its absorption of light.Read moreRead less
Hybrid cooling for coal fired power stations. Water shortage is a nation wide problem facing Australian industries. The project will directly benefit the Victorian power industry through water saving. If the new proposed hybrid cooling system concept is proved to be practically feasible, it will put the Australian power industry in a strong competitive position in terms of its efficiencies and waste heat recovery technology.

The project will directly benefit the Victorian power industry through water saving. If the new proposed hybrid cooling system concept is proved to be practically feasible, it will put the Australian power industry in a strong competitive position in terms of its efficiencies and waste heat recovery technology. Lowering the temperature of water into the cooling tower by 2 degree, by using the hybrid cooling system, it would save over 17,500,000 tons of makeup water per year for the Victorian power industry alone. At the same time, the waste heat recovered by the heat pump can be fed back to the power generation cycle. Read moreRead less
Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx. Coal combustion provides over 80% of the electricity produced in Australia, with the power stations being major emitters of the pollutants NOx and SOx. This project will potentially lead to a new technology to simultaneously remove NOx and SOx in a single and economical process, eliminating the secondary waste streams that disadvantage current competing technologies. This will provide: significant environmental benefits f ....Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx. Coal combustion provides over 80% of the electricity produced in Australia, with the power stations being major emitters of the pollutants NOx and SOx. This project will potentially lead to a new technology to simultaneously remove NOx and SOx in a single and economical process, eliminating the secondary waste streams that disadvantage current competing technologies. This will provide: significant environmental benefits for Australia in reducing these dangerous atmospheric pollutants; economic advantage to our power stations by enabling cheaper, more efficient technologies and consolidate Australia's leading position in the world in air pollution control.
