Title:
LIQUID FUEL PRODUCTION PROCESS FROM CELLULOSE BIOMASS
Document Type and Number:
WIPO Patent Application WO/2008/095349
Kind Code:
A1
Abstract:
A liquid fuel production process from cellulose biomass comprises the following steps: (1) providing a mixture of cellulose and water; (2) subjecting the obtained mixture to hydrolysis and catalytic hydrogenation under the presence of acid to obtain mono-sugar alcohol and optional solid material lignin, or subjecting the obtained mixture to hydrolysis to obtain monosaccharide; (3) esterifying the obtained mono-sugar alcohol with C2-C5 organic acid to obtain a liquid fuel II, or subjecting the obtained mono-sugar alcohol or monosaccharide to dehydration/hydrogenation to obtain an organic liquid fuel I consisting of alkanes. This process avoids the loss of organic carbon atoms during fermentation, and the sugar derived from cellulose biomass can be converted to organic carbon in the liquid fuel. The lignin produced by the process can be used for preparing aromatics.
