Title:
HYDROGENOLYSIS OF LIGNIN-CONTAINING SUPPLY RAW MATERIAL
Document Type and Number:
Japanese Patent JPS5843932
Kind Code:
A
Abstract:
A lignin-containing feed material in particulate form is mixed with a process-derived slurrying oil and fed into an ebullated catalyst bed hydrocracking reactor. Reaction conditions are maintained at 650 DEG -850 DEG F. temperature, 500-2500 psig hydrogen partial pressure and space velocity of 1.0-10 wt. lignin/hr./wt. catalyst. The reaction products are phase separated to recover hydrogen and slurrying oil, and the resulting liquid stream is passed to a thermal hydrodealkylation step. The reacted stream is fractionated to produce phenol and benzene products, along with a heavy alkylated material which is recycled to the hydrodealkylation step to increase the yield of phenol and benzene.
