This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia. The facility will consist of a high-pressure thermal gravimetric analyser (TGA) able to operate at up to 5 MPa, which will be coupled to a mass spectrometer (MS) for identification and quantification of gaseous reaction products. The facility constitutes unique and significant national research infrastructure for the simultaneous acquisition of mass loss kinetic measurements together with characterisation and quantification of emission rates of gaseous fragments generated in the reaction. As a major outcome, the facility will provide a means for consistent investigation of kinetics of elemental reactions occurring in solids, or on solid surfaces during pyrolysis and gasification processes at high pressure.
