Abstract:
1. A process for conversion of a lignin material to a bio-fuel, 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 combinations thereof; wherein said partially hydrodeoxygenated product is substantially comprised of aromatic compounds having a single oxygen moiety substituent; and c) reacting the product of step (b) in a hydroprocessing step to form a bio-fuel.
