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.

This project aims to understand the interaction of light responsive nano-metals and metal oxide supports in photo-thermal catalysis, and channel light and heat to efficiently drive catalytic reactions. From this understanding, it will develop principles to activate the active site of metal oxides and control catalytic activity with high selectivity and stability. It will use this knowledge to selectively oxidate methane and oxidative coupling of methane reactions. The expected outcome is an inexpensive green catalysis method for chemical manufacture. This should lower the amount of waste, decrease energy consumption and improve human health, finite global resources and quality of life.Read moreRead less

This project aims to generate new knowledge for the development of a novel hot gas cleaning technology. This project expects to understand the mechanisms of tar reforming using biochar as a renewable catalyst, which can avoid the problems associated with the catalyst deactivation and catalyst disposal if conventional supported catalysts are used.

Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and s ....Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.Read moreRead less

Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based ....Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based waste (including food, garden, paper, and wood) and fossil-fuel derived materials (plastics). Using an innovative and environmentally-sustainable catalytic process, the outcomes of this project are aimed alleviating Australia’s dependence on diesel fuel imports and better waste management solutions in Australia.Read moreRead less
