Mike Kleinert was born in 1976 in Stadthagen, Germany. After chemistry studies in Hannover and in S.V. Ley's group in Cambridge, UK, he received his diploma 2001 in Hannover having worked on natural product synthesis in the group of H.M.R. Hoffmann. His PhD studies were performed in the field of carbohydrates at the interface of synthetic organic and applied biological chemistry in Th.K. Lindhorst's group in Kiel, Germany. After his doctorate in 2005 he begun working as postdoctoral researcher in the group of T. Barth at the Unit for physical-, petroleum- and process chemistry at the University of Bergen, Norway. Here he invented a thermochemical conversion approach (solvolysis with formic acid) for the production of oxygen-depleted liquid fuel compounds and platform chemicals from wood lignin in the frame of the international collaborative research project "Cost effective production of renewable liquid biofuel and biochemicals from Scandinavian wood materials".
His main research concentrates on the various aspects of the integrated biorefinery concept and the valorisation of different biomass feedstocks towards liquid and solid bioenergy carriers as well as value-added platform chemicals.
Hence, woody biomass such as SRF or forestric residues, but also agricultural or industrial residues such as straw or lignin are among the source materials which can lead to value-added products in the scope of liquid transportation fuels, phenolic building blocks or novel solid bio-fuels.
Thermochemical transformation routes such as pyrolysis, solvolysis, liquefaction, torrefaction and hydrothermal carbonisation are the core techniques elucidated to
match the different biomass sources and appropriate conversion/pre-treatment strategies to form the required products effectively and efficiently.
Currently he is employed by a German company working in the field of biomass utilisation towards solid bio-fuels via the hydrothermal carbonisation (HTC) approach.
Mike Kleinert was awarded the Meltzer prize 2008 for young researchers:
