Title:
CONTINUOUS PROCESS FOR CONVERSION OF LIGNIN TO USEFUL COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2013/124460
Kind Code:
A3
Abstract:
An integrated process for the conversion of a ligno-cellulosic biomass feedstock comprised of lignin and carbohydrates, said process comprising: A. Pretreating the ligno-cellulosic biomass feedstock with treatment water which includes steam explosion to create a pre- treated ligno-cellulosic biomass feedstock, B. Converting at least a portion of the carbohydrates of the pre-treated ligno-cellulosic biomass feedstock into carbohydrate conversion products selected from the group consisting of alcohols, polyols, glucans, gluco-lignins and cellulose, C. Charging the lignin from the ligno-cellulosic biomass feedstock into a lignin conversion reactor having a lignin conversion pressure via a stream comprised of lignin from the ligno-cellulosic biomass feedstock, D. Converting at least a portion of the lignin of the pre-treated ligno-cellulosic biomass feedstock into lignin conversion products by contacting the lignin with hydrogen in the presence of a first catalyst at a lignin conversion temperature,
