Methods of producing stable lignin phenolic oil

Abstract

The present invention relates to a method of producing a stable lignin phenolic oil, where the method comprises providing a lignin; pre-treating the lignin with a base solution, where the base solution has a pH of 8 or above; and hydrogenating the pre-treated lignin to produce a stabilized lignin phenolic oil. The present invention further relates to a method of producing a stable lignin phenolic oil, the method comprising: providing a non-recalcitrant lignin; solubilizing the lignin in a solvent; and hydrogenating the solubilized lignin to produce a stabilized lignin phenolic oil.
