Catalytic Conversion of Waste Plastics to Hydrocarbon Fuels. This project aims to investigate the catalytic conversion of waste plastics to liquid fuels. Plastics comprise about 20% of municipal waste by volume, and are a major environmental concern as the present practice of disposal by landfilling has long-term hazard potential and is unsustainable. We propose to study the kinetics of the catalytic degradation of pure component plastics as well as their mixtures in a laboratory screw extrusi ....Catalytic Conversion of Waste Plastics to Hydrocarbon Fuels. This project aims to investigate the catalytic conversion of waste plastics to liquid fuels. Plastics comprise about 20% of municipal waste by volume, and are a major environmental concern as the present practice of disposal by landfilling has long-term hazard potential and is unsustainable. We propose to study the kinetics of the catalytic degradation of pure component plastics as well as their mixtures in a laboratory screw extrusion reactor, compare alternative catalysts, and develop process models to be used for scale up. The process and know-how developed will contribute to sustainable development, and provide an internationally competitive advantage to Australia.Read moreRead less

Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features.

This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less

This project seeks to incorporate non-equilibrium molecular dynamics calculations into particle scale models for adsorption kinetics. Molecular dynamics calculations will be performed for hydrocarbon molecules in small pores to obtain transport coefficients in pores of various sizes, at various bulk gas pressures and temperatures. These transport coefficients will be used in particle scale models to obtain a dynamic model, which will be utilised to interpret experimental data from the literature as well as that being obtained in our laboratory. Such first principles-based modelling has not been performed before at the particle scale, and will mitigate the empiricism in existing approaches.Read moreRead less

Relative Permeability in Coal. This project aims to deliver a better model for coal relative permeability to improve the management of coal seam gas reservoirs. Coal relative permeability is a key factor in reservoir models; however, current understanding of relative permeability is wrong for coal systems and predictions based on it are misleading.

This project aims to deliver a better model for coal relative permeability to improve the management of coal seam gas reservoirs. Coal relative permeability is a key factor in reservoir models; however, current understanding of relative permeability is wrong for coal systems and predictions based on it are misleading. Relative permeability is currently carried over from conventional gas reservoirs as a function of the degree of water saturation only. This misunderstands the physical differences between coal and other rocks as gas reservoirs, fails to recognise the determinants of coal relative permeability, and misrepresents the flow system. This project seeks to provide a phenomenologically-based understanding and functional relationship for coal-relative permeability based on the principles than govern physical flow interactions.Read moreRead less
