This project aims to develop nanoscale heating technique using AC magnetic field for efficient synthesis of ammonia, widely used for fertiliser and having potential for hydrogen storage. This project is to introduce nanoscale heating concept by heating catalyst only but not solution in electrochemical catalysis to achieve high catalytic activity. Expected outcome is the creation of low cost catalysts having high selectivity and formation rate for ammonia production. This unique technology has the potential to replace current ammonia production based on Haber-Bosch process, which consumes 2% of world energy and contributes 3% of overall CO2 emission. The project provides opportunities for new industries that will benefit Australian economy.Read moreRead less
3-D Printed Catalytic Monoliths for Energy Efficient Carbon Conversion. Carbon Capture and Utilisation (CCU) is an essential pathway for reducing carbon in the Earth's atmosphere. However a major hurdle in the carbon utilisation part is that the conversion technologies often rely on energy derived from fossil sources. Electrification of carbon conversion processes can overcome this hurdle by providing this energy via renewables.

Carbon Capture and Utilisation (CCU) is an essential pathway for reducing carbon in the Earth's atmosphere. However a major hurdle in the carbon utilisation part is that the conversion technologies often rely on energy derived from fossil sources. Electrification of carbon conversion processes can overcome this hurdle by providing this energy via renewables. This project aims to develop an electrically powered energy efficient catalytic process for carbon conversion. A modular 3-D printed monolithic catalytic reactor prototype powered by induction or resistive heating will be developed to minimise energy loss in the carbon conversion process. An expected outcome of this project is translation of this prototype in a CCU pilot scale facility.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
In-situ catalytic upgrading of bio-oil using scrap tyre char. This project aims to develop advanced, cost-competitive catalysts based on scrap tyre char, an otherwise low-value by-product.

Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate s ....Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate smelting strategies and control methods. As a result, transportation of toxic materials overseas will be eliminated, environmental hazards will be reduced and our sustainable use of metals will be increased.Read moreRead less
The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding ....The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding of the exact role of carbon layers on mineral surfaces in both preg-robbing and leaching is essential to devise process strategies that could lead to improved extraction.Read moreRead less

The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as pr ....The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as products from the copper cyanide containing streams. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the discharge of cyanide species into tailings dams.Read moreRead less
