PROCESS FOR LIQUEFYING A CELLULOSIC MATERIAL

摘要

A process for liquefying a cellulosic material is provided comprising hydrolysing the cellulosic material in the presence of an acid catalyst in a solvent mixture to produce a liquefied product, wherein the solvent mixture contains water and in the range of 5 to 95 wt % of a co-solvent and wherein the co-solvent is present in an amount of less than or equal to 90% by weight based on the weight of water and co-solvent, which co-solvent comprises one or more polar solvents, and wherein the solvent mixture is at least partly recycled.
