Title:
CONTINUOUS PROCESS FOR CONVERSION OF LIGNIN TO USEFUL COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2013/124458
Kind Code:
A3
Abstract:
A continuous process for the conversion of lignin feedstock comprised of lignin and glucans, said process comprising: Slurry creation of a slurry comprised of lignin from the lignin feedstock, Charging the slurry comprised of lignin into a lignin conversion reactor having a lignin conversion pressure, wherein the pressure of the slurry comprised of lignin is higher than the lignin conversion pressure, Converting the lignin of the slurry comprised of lignin into lignin conversion products by contacting the lignin with hydrogen in the presence of a first catalyst at a lignin conversion temperature, and Removing the lignin conversion products from the lignin conversion reactor.
