摘要： It is disclosed a process for increasing the enzymatic accessibility of a thermally treated ligno-cellulosic biomass feedstock which has been thermally treated at a severity factor. The process comprises a step of fiber shives reduction, for reducing the amount of long shives. The thermally treated ligno-cellulosic biomass after fiber shives reduction is characterized by having an increased glucans accessibility and by forming a slurry having a low viscosity.

摘要： A process for producing polyols from a low viscosity slurry comprising a thermally treated ligno-cellulosic biomass which has been subjected to a fiber shives reduction step is provided. Specifically, a continuous process for catalyzing the formation of polyol products, such as ethylene glycol and propylene glycol, from the low viscosity slurry is provided.
