Abstract:
1. A process for conversion of a lignin material to substantially phenolic compounds comprising: a) Subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin; b) Subjecting the partially depolymerized lignin to a stabilization/partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product, said process being carried out in the presence of a catalyst containing one or more metals selected from the group consisting of Group VI metals of the Periodic Table, Group VIII metals of the Periodic Table, vanadium and mixtures thereof; wherein said partially hydrodeoxygenated product is substantially comprised of aromatic compounds having a single oxygen moiety substituent, and c) Treating the product of step b) in a mild hydrocracking process to produce substantially monomeric phenols.
