Abstract
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.
