Title:
PROCESS FOR LIQUEFYING A CELLULOSIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/141546
Kind Code:
A3
Abstract:
A process for liquefying a cellulosic material to produce a liquefied product, which process comprises contacting the cellulosic material simultaneously with - an acid catalyst; - a solvent mixture containing water and a co-solvent, which co-solvent comprises one or more polar solvents and which co-solvent is present in an amount of more than or equal to 10% by weight and less than or equal to 95% by weight, based on the total weight of water and co-solvent; - a hydrogenation catalyst; and - a source of hydrogen. Products obtained from the above process and use of such products to prepare biofuels.
