Claim:
1. A continuous process for the conversion of lignin feedstock comprised of lignin and glucans, said process comprising: A. Slurry creation of a slurry comprised of lignin from the lignin feedstock which is a stillage lignin wherein the slurry creation comprises the steps of: B. 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 in the range of 80 to 245 bar, C. 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 D. Removing the lignin conversion products from the lignin conversion reactor while the reaction is occurring.
