The Effects of Pyrolysis Conditions on Combustion and Gasification Reactivities of Biomass Chars and the Quality of Their Ash. Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass.

Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass. Many of the challenges associated with the thermal conversion of biomass relate to its char characteristics. The aim of this project is to gain a fundamental understanding about the impact of reaction conditions during the pyrolytic stage on the structural and compositional transformations of the resultant char, its combustion and gasification reactivities, and the release of inorganic matter and ash formation. This holistic and integrated approach should reveal the underlying science necessary to support existing and future biomass use.Read moreRead less
Combined Particle Image Velocimetry (PIV) and CFD modelling to study particle deposition in conduits. System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation inc ....Combined Particle Image Velocimetry (PIV) and CFD modelling to study particle deposition in conduits. System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation including flow visualization by PIV to systematically investigate the effect of channel geometry and flow on deposit formation. The outcomes of the project will result in a better understanding and formulating of the effect of geometry on deposition of colloidal particles and ionic species on the surfaces. The results contribute not only towards the mitigation processes for unwanted deposition; it also advances the knowledge in coating applications.Read moreRead less
Combustion Characteristics of Biomass Chars in Pressurised Circulating Fluidised Bed Reactors. The development of new, cleaner methods of electricity generation, such as biomass-based integrated gasification combined-cycles and hybrid-cycle pressurised fluidised-bed combustion, have highlighted the need for a greater understanding of the combustion characteristics of biomass chars at high pressures and temperatures. The aim of this project is to gain a clearer understanding of the underlying mec ....Combustion Characteristics of Biomass Chars in Pressurised Circulating Fluidised Bed Reactors. The development of new, cleaner methods of electricity generation, such as biomass-based integrated gasification combined-cycles and hybrid-cycle pressurised fluidised-bed combustion, have highlighted the need for a greater understanding of the combustion characteristics of biomass chars at high pressures and temperatures. The aim of this project is to gain a clearer understanding of the underlying mechanisms that control the combustion of biomass chars in pressurised circulating fluidised-bed (PCFB) reactors. The fundamental knowledge gained in this project will have immediate practical applications as modern PCFB reactors are considered to be the most suitable systems for the combustion of biomass char particles.Read moreRead less
Characterisation of Pyrolytic Thermal Regions in Coal Macerals using Computer Aided Thermal Analysis. The research will assist in the fundamental understanding of coal pyrolysis mechanisms. All coal contains proportions of different fossilised plant material, which behaves differently when heated. This proposal studies thermal behaviour of the density separated fractions in Australian coals using a highly sensitive technique.

The research will assist in the fundamental understanding of coal pyrolysis mechanisms. All coal contains proportions of different fossilised plant material, which behaves differently when heated. This proposal studies thermal behaviour of the density separated fractions in Australian coals using a highly sensitive technique. The characterisation adds value and use to current coal reserves and is aimed towards producing an advanced modelling capability to promote efficient coal usage in existing and future technologies. Such innovative approaches support the sustainability of Australian coal reserves, particularly in the transition towards decarbonised energy.Read moreRead less
Scaleable Microstructured Chemical Process Systems. This project seeks to revolutionize the way bulk chemicals are made industrially. By combining highly integrated process designs, with profound process intensification, we will create the basis for chemical process technology that is efficient and economical at relatively small scale.

This project seeks to revolutionize the way bulk chemicals are made industrially. By combining highly integrated process designs, with profound process intensification, we will create the basis for chemical process technology that is efficient and economical at relatively small scale. This development will reinvigorate the Australian chemical industry, with enormous benefits to the country in terms of improved security of supply of chemicals and fuels and reduced trade deficit. This new type of plant will be scaleable and without the technical risk normally associated with plant scale-up. At the smallest scale, it will be mobile and able to utilise remote and dispersed feedstocks such as stranded natural gas, coal bed methane, or biogas. Read moreRead less
