Three step mechanical process for pre-treatment of biomass
development of a Pulping process for lignocellulosic biomass based on mechanical treatment
Within the Cluster of Excellence "Tailor-Made Fuels from Biomass" the selective conversion process from biomass into the third generation of biofuels is explored. Since pre-treatment makes biomass accessible to any further solution and chemical or enzymatic transformation, it is a step which is necessary and essential for the entire downstream process. The aim of this project is to develop a decomposition process for wood and other lignocellulosic biomass based on mechanical treatment. It is achieved in a three-stage process by means of a cutting mill, a screw extruder and an intensive mixer. The main subject focuses on the improvement of the screw extruder in order to disrupt the cell structure of the lignocellulosic biomass and increase its solubilization efficiency in ionic liquids.
