Lignocellulosic fractionation

Fractionating lignocellulosic biomass efficiently is far from being a mundane or trivial task. Within plant biomass (lignocellulose) there are several components (cellulose, hemicellulose and lignin), each of which carries their own requirements for dissolution. To enable a holistic valorization of biomass, those components should be fractionated to individual streams of cellulose, hemicellulose and lignin to…

Organosolv fractionation of lignocellulosic biomass

Dr. Leonidas Matsakas with the organosolv reactor in the Institue of Biochemical Process Engineering, at Luleå University of Technology, Sweden You are working on the “Organosolv fractionation of lignocellulosic biomass” and are at the beginning of the FLEXI-GREEN FUELS process. Could you describe in simple words the organosolv process? Organosolv is a process in which…

Solvent recovery – How to re-use the key ingredient of the process

Bringing a novel process all the way to the market is not an easy task. A key factor to succeed is to minimize all losses that can potentially destroy the overall profitability. In Flexi-Green Fuels, KIRAM has studied and validated the delicate process of recovering the solvent used in Organosolv to enable efficient recirculation. One…
