Synthesis of oligomers in dense carbon dioxide. The aim of the project is to develop a novel technique for the synthesis of low molecular weight polymers (oligomers) using dense carbon dioxide as a polymerisation solvent. The use of elevated pressure is the major impediment to the commercialisation of such technology. The technique proposed in this project will enable oligomers to be produced at greatly reduced operating pressures and may lead to a more general procedure for conducting other t ....Synthesis of oligomers in dense carbon dioxide.

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.

Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenh ....Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenhouse gases) and oxygen to produce selectively methanol and hydrocarbons from a natural gas feedstream in a controlled manner. A single step process for natural gas conversion utilising waste green-house gases is expected to be of great benefit to the Australian economy, environment and energy securityRead moreRead less

Emulsion polymerization is of major industrial importance. In addition to process efficiency, the use of water as the reactor medium provides environmental benefits. This proposal is aimed at building an integrated framework to analyse, model, control and optimise emulsion polymerisation systems in order to understand, design and operate such complex systems to obtain desired polymer product characteristics. Complex kinetic, transport and evolution equations will be analysed and solved for predicting and controlling key product properties. This project will provide not only a significant advance in fundamental knowledge of polymerisation systems but will also enable production of cost-effective ?designer polymers? for a wide-range of applications.Read moreRead less
