Hallett, Jason P. - Imperial College London - Department of Chemical Engineering

个人简介

Dr Jason Hallett received his PhD in Chemical Engineering from the Georgia Institute of Technology. He joined Imperial College, first with a Marshall-Sherfield Postdoctoral Fellowship in Sustainable Chemistry and in 2014 was appointed a Senior Lecturer in the Department of Chemical Engineering. He has authored over 60 articles and holds 4 patents. His current research interests involve the solvation behaviour of ionic liquids and the use of ionic liquids in the production of lignocellulosic biofuels and sustainable chemical feedstocks. This research is supported by both the EPSRC and industry. Dr Hallett currently serves as theme leader for Biorenewables and Biofuels research in the Manufacturing Futures Lab and for Underpinning basic sciences and engineering in the Industrial Biotechnology Hub.

研究领域

Ionic Liquid Based Biorefining: This research aims to establish the core technologies and opportunities in an ionic liquid based biorefinery and identify the key science underpinning this concept. The biorefinery will produce biofuels and chemical feedstock materials from lignocellulosic biomass by first using specially designed ionic liquids to separate the biomass components (lignin, cellulose, hemicelluloses). All aspects of the separations process and several aspects of the conversions (specifically, the initial chemical- and bio-catalytic breakdown steps) are included, particularly important questions related to ionic liquid impact and recovery. The polysaccharides that are separated (cellulose, hemicelluloses) are enzymatically hydrolysed to fermentable sugars, with the impact of residual ionic liquid minimalized through a multi-pronged strategy involving solvent design and novel separations. This requires an investigation into the specific interactions of ionic liquids with the biological catalysts (enzymes, whole cells) vital to bioconversions, utilizing a variety of chemical biology-based tools. This is by nature a multi-disciplinary research problem. The underpinning molecular-scale chemical interactions of ionic liquids with biomass, proteins and whole cells will determine the productivity of the biorefinery. The impact of these individual elements on the overall process requires a detailed understanding of both the complex intermolecular interactions driving ionic liquid behavior and an appreciation for how these interactions can impact a chemical process. This places the research firmly at the interface between chemistry and chemical/biomolecular engineering.
