Hydrodynamics of Bubble Column Reactors. This project will study the hydrodynamics of bubble columns with the aim of optimising these reactors for offshore gas-to-liquid plants. 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 ....Hydrodynamics of Bubble Column Reactors.

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
Helium recovery from liquefied natural gas waste stream using nanoporous mxene materials. The waste streams from many liquefied natural gas (LNG) industries still contains valuable helium, a possible next mineral to sustain our economic growth. This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials. This project will seek to understand the assembling behaviour of these nano-sized Mxene flakes and their molecular sieving properties.

The waste streams from many liquefied natural gas (LNG) industries still contains valuable helium, a possible next mineral to sustain our economic growth. This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials. This project will seek to understand the assembling behaviour of these nano-sized Mxene flakes and their molecular sieving properties. Australia is playing a leading role in the global liquefied natural gas (LNG) production and trade. This project expects to further position Australia at the forefront of intellectual leadership in the field of gas processing and material development. This will have significant benefits, such as further improving these LNG projects economics by cost-effectively producing helium as a valuable by-product via advanced porous nano-materials.Read moreRead less
Biochar as a renewable catalyst for hot gas cleaning. 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. Expected outcomes of this project include a theoretical framework and a kinetic model describing ....Biochar as a renewable catalyst for hot gas cleaning. 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. 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
