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

This project aims to make ground-breaking advances in the modelling of transport in disordered nanoporous materials by uncovering the interfacial barriers that are critical to the entry and exit of molecules from their nanostructure. The expected outcome is an efficient new simulation tool to simultaneously quantify interfacial transport resistances and system size-dependent internal transport coefficients. This is intended to be achieved through simulations and experiments on the adsorption and dynamics of targeted gases in carbons with distinctly different nanostructures, enabling the optimal design of a wide range of emerging nanotechnologies for membrane separations, kinetic molecular sieving, catalysis, and gas and electrochemical energy storage.Read moreRead less
Multi-scale Process Modelling for Intelligent Control. Processing and manufacturing systems are inherently multi-scale in their behaviour. From the molecular scale to the enterprise-wide scale. This and other attributes of the individual models create difficulties in the design and control of such systems.

Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less

Tablets represent the preferred method of dose delivery in the pharmaceutical industry, with over 80% of the market. PressFit - gelcaps have recently been developed, which encase a tablet core within a gelatin coating. The product combines the consumer appeal of capsules with the processing convenience of tablets, and provides a high degree of tamper-resistance. An important issue is that the caplets are required to have very precise dimensional precision, an issue not previously of high priority for tabletting . This project seeks to enhance the competitive advantage of this new technology, through a combination of advanced mathematical modeling supported by experiments.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. In the pre ....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. 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
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. Relative permeability is currently carried over from conventional gas reservoirs as a function of the degree of water saturation only. This misunders ....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. 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
The Effect of Fines Particles on Production and Permeability of cbm Reservoirs. Coalbed methane (cbm) energy resources in Australia exceed $20b in value. One of the production issues with recovering cbm is fines that are created or exist in the coal, which block gas flow to the recovery wells and damage downstream equipment. Understanding how fines are created and migrate within gas wells and then overcoming this problem, the purpose of this research, could deliver additional gas production wort ....The Effect of Fines Particles on Production and Permeability of cbm Reservoirs. Coalbed methane (cbm) energy resources in Australia exceed $20b in value. One of the production issues with recovering cbm is fines that are created or exist in the coal, which block gas flow to the recovery wells and damage downstream equipment. Understanding how fines are created and migrate within gas wells and then overcoming this problem, the purpose of this research, could deliver additional gas production worth over $1.8billion and reduce maintenance costs related to cbm extraction by $25m per year.Read moreRead less
