High purity formaldehyde production from carbon oxides. This project aims to investigate the detailed reaction mechanism of a green chemistry route of producing formaldehyde by reducing carbon monoxide and carbon dioxide in liquid phase. Formaldehyde is a widely used feedstock for chemical industries, but is not considered a green chemical because it is produced using natural gas as the feed, which loses over 61 per cent of energy. This project will maximise the yield and purity of the product, ....High purity formaldehyde production from carbon oxides. This project aims to investigate the detailed reaction mechanism of a green chemistry route of producing formaldehyde by reducing carbon monoxide and carbon dioxide in liquid phase. Formaldehyde is a widely used feedstock for chemical industries, but is not considered a green chemical because it is produced using natural gas as the feed, which loses over 61 per cent of energy. This project will maximise the yield and purity of the product, making it commercially viable. This project’s method for producing formaldehyde is expected to reduce the capital cost and energy losses.Read moreRead less
Particle motion and particle-convective heat transfer near the walls of fluidized beds. Background: Fluidized bed technology has important industrial applications ranging from petrol production to mineral processing for metal production. Such processes take advantage of the high rates of heat transfer in gas-fluidized beds.
Objective of project: To improve understanding and modelling of heat transfer in gas fluidized beds through the application of state-of-the-art experimental (Positron Emiss ....Particle motion and particle-convective heat transfer near the walls of fluidized beds. Background: Fluidized bed technology has important industrial applications ranging from petrol production to mineral processing for metal production. Such processes take advantage of the high rates of heat transfer in gas-fluidized beds.
Objective of project: To improve understanding and modelling of heat transfer in gas fluidized beds through the application of state-of-the-art experimental (Positron Emission Particle Tracking) and modelling (Discrete Element Method simulation) techniques.
Expected outcomes of project: New knowledge of the mechanisms of fluidized bed heat transfer. Improved the prediction of heat transfer coefficients with consequent improvements in the design and operation of fluidized bed processes.

Summary
Characterisation Equipment for Advanced Gas Separation Applications. The proposed research will lead to the synthesis of new advanced materials capable of performing new and existing separations more efficiently than previous methods. We therefore expect the new materials to directly benefit the community through improved removal and recovery of a wide range of pollutants which would otherwise enter the environment. This research is directly aligned to the National Research Priority of Frontie ....Characterisation Equipment for Advanced Gas Separation Applications.

Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less
Advanced chemical recycling of mixed plastics for monomer recovery. This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise ....Advanced chemical recycling of mixed plastics for monomer recovery. This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
