Along with experiments using the state-of-art techniques such as the particle image velocimetry, radioactive particle tracking, electrical capacitance tomography and optical probes, computational fluid dynamics simulations will be conducted to gain a deeper insight into bubble-induced turbulence and regime transitions in these reactors. This information will then be used to devise scale-up strategies of these complex and industrially important equipment.Read moreRead less
Influence of adsorbed surfactants on three phase contact line motion at high capillary number. The interaction between thin films and solid surfaces underpins the performance of a number of value-adding industrial processes, most notably metallurgical coating operations. Typically, these operations are performed at speeds well beyond the range of existing models, thereby limiting their value when changes in operation occur or when there are problems with product quality. Existing models are also ....Influence of adsorbed surfactants on three phase contact line motion at high capillary number. The interaction between thin films and solid surfaces underpins the performance of a number of value-adding industrial processes, most notably metallurgical coating operations. Typically, these operations are performed at speeds well beyond the range of existing models, thereby limiting their value when changes in operation occur or when there are problems with product quality. Existing models are also limited by their inability to account for the presence of surfactants commonly used throughout industry. This study will produce a capability for predicting how velocity and local changes in molecular composition affect the wetting/dewetting of coated surfaces.Read moreRead less

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. Expected outcomes of this project include a theoretical framework and a kinetic model describing the catalytic reforming of tar as part of the hot gas cleaning during the conversion of biomass. The technology will contribute to Australia’s improved energy security and reduced carbon dioxide (CO2) emissions in the carbon-constrained future.Read moreRead less
A New Spin on Liquid Hydrogen: Controlled Cold Energy. While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through t ....A New Spin on Liquid Hydrogen: Controlled Cold Energy. While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through the provision of controllable refrigeration (so-called 'cold energy') following regasification. In particular we will measure, optimise and exploit the highly endothermic catalysed conversion of para- to ortho- hydrogen, which can provide up to 525 kJ/kg of cooling at convenient temperatures.

This project aims to develop a novel technology from biomass pyrolysis for coproducing a diesel/biodiesel/bio-oil blend as a liquid transport fuel for local use and a high-quality bioslurry fuel suitable for transport to centralised stationary applications. The technology aims to address key issues associated with current biofuel production from biomass pyrolysis due to the undesired high acidity, poor stability and high oxygen content of bio-oil. The liquid transport fuel is expected to be produced without the expensive bio-oil hydrotreating for deep de-oxygenation, which is otherwise required for using bio-oil as feedstock in conventional petroleum refining process. Both biofuel products can be adoptable for wide applications in the existing vast infrastructure.Read moreRead less

Novel Characterization of Porous Structure and Surface Chemistry of Carbon. The aim of this project is to develop novel characterisation methods that probe the structure and surface chemistry of carbons, ranging from highly graphitised thermal carbon black through ordered mesoporous carbon to disordered porous activated carbon.

The aim of this project is to develop novel characterisation methods that probe the structure and surface chemistry of carbons, ranging from highly graphitised thermal carbon black through ordered mesoporous carbon to disordered porous activated carbon. The project plans to develop a new generic molecular model based on wedge-shaped pores. Conventional parallel sided pore models fail to account for real structures and therefore for the physics of adsorption in real materials. The project then plans to back the theoretical model with high-resolution experimental measurements. It is expected that the model will unify the structural analysis for all carbons and account for all experimental isotherms within a rational and physically plausible framework.Read moreRead less
Bio-oil/char slurry from biomass for co-combustion in coal power plants: achieving power generation with a significant reduction of CO2 emission. This project will develop an advanced co-combustion technology of bio-oil/char slurry (i.e. bioslurry), prepared from biomass pyrolysis products, and coal in the existing coal-fired power plants for achieving significant CO2 reduction. It will enhance Australia's competitive advantage through high impact scientific and technological innovations.
Fires of halogenated industrial chemicals and their impact on the Australian environment. Recent large fires of industrial chemicals in Australia led to significant environmental pollution. In this project, we will develop sophisticated techniques to assess pollutants formed in fires of commonly used industrial chemicals. The results will find immediate applications in training fire brigades in their response to chemical fires.
