Reactivity of Carbon-Carbon Composites. This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temper ....Reactivity of Carbon-Carbon Composites. This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temperatures on the relationship between anode microstructure and reactivity in oxygen as well as carbon dioxide will be investigated, and optimum process conditions determined for minimum reactive carbon loss during smelting.Read moreRead less
A Comprehensive Kinetic Model for Sulfur Reactions in Combustion, Gasification, and Chemical Processing. Sulfur chemistry in high temperature processes is poorly understood, leading to uncertainties in the design of these processes and in the control of their emissions. In particular, new approaches to lowering greenhouse emissions which depend on the combustion and gasification of coal, biomass, or refuse-derived fuel, such as integrated gasification combined cycle processes, are especially aff ....A Comprehensive Kinetic Model for Sulfur Reactions in Combustion, Gasification, and Chemical Processing. Sulfur chemistry in high temperature processes is poorly understood, leading to uncertainties in the design of these processes and in the control of their emissions. In particular, new approaches to lowering greenhouse emissions which depend on the combustion and gasification of coal, biomass, or refuse-derived fuel, such as integrated gasification combined cycle processes, are especially affected by these uncertainties. This project seeks to combine experimental measurements and quantum chemical modelling to produce a detailed mechanistic model for the reactions of sulfur in high-temperature systems. Such a model will provide designers with a tool to optimise these complex interacting systems.Read moreRead less

High framing rate stereoscopic particle image velocimetry (HFR SPIV) facility. This proposal seeks to establish a specialised high framing rate stereoscopic particle image velocimetry (HFR SPIV) facility for the measurement of rapidly changing velocity fields in complex flows. The proposed facility is currently not available in Australia and is significant in that it provides a continuous time sequence of rapidly changing 3D velocity fields in a two-dimensional plane.

This proposal seeks to establish a specialised high framing rate stereoscopic particle image velocimetry (HFR SPIV) facility for the measurement of rapidly changing velocity fields in complex flows. The proposed facility is currently not available in Australia and is significant in that it provides a continuous time sequence of rapidly changing 3D velocity fields in a two-dimensional plane. The facility will provide experimental validation for models and theories developed for fast transient flows in non-periodic time dependent flows, multi-phase flows, solid mechanics and natural convection.Read moreRead less
Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium n ....Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium nitrate. Ammonium nitrate crystallisation, which significantly reduces the stability of emulsion explosives, will be examined using both chemical and microscopic tools. The outcomes of this research will provide a scientific basis that underpins the development of safe and cost-effective explosives for applications in dangerous reactive mining grounds.Read moreRead less

This proposal seeks to establish a specialised Particle Image Thermometry / Velocimetry (PITV) facility for simultaneous three-dimensional measurements of global temperature and velocity fields in complex flows. The proposed facility is needed to obtain experimental validations for theories and models developed for complex reacting and non-reacting flows that are strongly influenced by transient behaviour. Applications of PITV include, but are not limited to, low-temperature reacting flows, mixing, jets, wakes, shear layers, time-dependent multiphase flows, unsteady turbulent flows, complex rotating machinery and other periodic flows, as well as natural convection studies.Read moreRead less
Process Systems for Distributed Chemical Manufacturing. This Project investigates a new paradigm for chemicals production, moving away from large-scale centralised plant to distributed manufacture in relatively small localised facilities. The Project is built on the conjunction of a revolutionary process systems synthesis methodology with a new approach to highly compact equipment manufacture.

This Project investigates a new paradigm for chemicals production, moving away from large-scale centralised plant to distributed manufacture in relatively small localised facilities. The Project is built on the conjunction of a revolutionary process systems synthesis methodology with a new approach to highly compact equipment manufacture. The Project is of great significance to developing countries and to smaller, remote economies such as Australia's, which cannot justify or compete with world-scale production facilities. We will develop our ideas in a case study and identify routes to practical implementation of this example in particular and of the new approach in general.Read moreRead less
Establishing the pathways of biomass decomposition in hot compressed water. Australia has significant under-developed biomass and brown coal resources which could feasibly be used to produce transport fuels and industrial chemicals. The successful conversion of these resources will offset the rising cost of petrochemicals, reduce oil import dependency, and in the longer term, address some of the challenges of climate change. We will directly address this problem by investigating the mechanism of ....Establishing the pathways of biomass decomposition in hot compressed water.

The successful conversion of these resources will offset the rising cost of petrochemicals, reduce oil import dependency, and in the longer term, address some of the challenges of climate change. We will directly address this problem by investigating the mechanism of conversion of biomass and brown coal resources to targeted chemical products, at laboratory and pilot scale, as a precursor to the development of a commercial biorefinery.Read moreRead less
