CONTINUOUS PROCESS FOR CONVERSION OF LIGNIN TO USEFUL COMPOUNDS.

摘要

This specification discloses a method to convert a lignin biomass feedstream to a converted lignin stream comprising aromatic compounds. The process comprises combining a lignin biomass feedstream comprising lignin, at least one solvent and at least one catalyst in a reaction vessel. Preferably the ratio of moles of catalyst to moles of lignin is in the range of between 4:1 and 15:1. The lignin biomass feedstream is then deoxygenated to a converted lignin stream at a deoxygenation temperature and a deoxygenation pressure for a deoxygenation time.
