Associate Professor Peter Ashman

Biography/ Background

Peter Ashman is an Associate Professor within the School of Chemical Engineering and leads the South Australian Coal Research Laboratory (SACRL). He is a Key Researcher within the University of Adelaide’s Centre for Energy Technology (CET), a senior member of the School of Chemical Engineering’s Microalgae Engineering Research Group (MERG) and a co-leader of the Institute for Minerals and Energy Resources’ Resource Recovery Program. Within the School of Chemical Engineering, he is Deputy Head of School, Director of Teaching & Learning and Director of Outreach.

 

During 1999-2006, A/Prof Ashman was Key Researcher and Program Co-Leader with the Cooperative Centre for Clean Power from Lignite, leading a large group at the University of Adelaide focussing on the fluidised-bed gasification of Victorian and South Australian low-rank coals for the high-efficiency generation of electricity via Integrated Gasification Combined Cycle (IGCC) and on fundamental research questions related to this technology. This work is continued by the South Australian Coal Research Laboratory (SACRL), based at the University of Adelaide’s Research Park at Thebarton.

 

SACRL, established in 2007, has a strong focus on the utilisation and performance of South Australian low-rank coals and other solids fuels, including biomass and waste fuels. SACRL includes a team of researchers with extensive industrial and research experience in the fields of combustion science and technology, particularly in relation to solids fuel combustion. The laboratory has facilities for the preparation, characterisation and handling of solid fuels and a range of laboratory-scale and semi-industrial equipment suitable for fundamental and applied research, process development, and process verification and troubleshooting. SACRL is currently working with Hybrid Energy Australia (a wholly-owned subsidiary of ASX-listed Strike Energy Limited) to demonstrate fluidized-bed gasification technology associated with their FuturGas coal-to-liquids project based on their high-sodium, high-sulfur coal deposit located at Kingston in South Australia. Other recent research has investigated the pyrolysis of Automotive Shredder Residue (ASR) and thermal processing (combustion and gasification) of winery biomass residues.

A/Prof Ashman is also active in research leading to the commercial exploitation of microalgae for the production of renewable biofuels. With his colleagues, Dr David Lewis (U. Adel.), Prof Michael Borowitzka (Murdoch U.) and other partners from Australia, India and China, he has been funded to demonstrate the technical and economic feasibility of a fully integrated process for biodiesel production from microalgae in saline water. In this work he is part of an Adelaide-based team focussing on the downstream processing (harvesting and lipid extraction) of the microalgae. He was also recently funded through an ARC Linkage project, with support from SQC Pty Ltd, to investigate the thermal processing of microalgae residue. This work will be undertaken using SACRL’s fluid-bed combustion and gasification facilities at Thebarton.
