Abstract:
Implementations of the disclosed subject matter provide a process for converting biomass into furfural. The process may include subjecting a pentosan-containing biomass material to an acid catalyzed digestion process in a digestion vessel to produce a digested product stream comprising C5-carbohydrates and solids comprising cellulose. The digested product stream may be separated into a liquid product stream and a solid product stream comprising lignin and cellulose. The solids product stream may be contacted with water and an organic solvent, thereby converting at least part of the lignin to a phenolic solvent. The C5-carbohydrate in the liquid product stream may be subjected to a dehydration reaction in the presence of an acid catalyst and a biphasic mixture comprising an aqueous phase and a water-immiscible organic phase, wherein the water-immiscible organic phase includes at least a portion of the phenolic solvent, to produce furfural or a furan derivative.

Claim (Index 2):
The process of  claim 1 , further comprising, prior to step (e), separating at least part of the phenolic solvent from the solvent product stream produced in step (d), and wherein the phenolic solvent in step (e) is at least a portion of the separated phenolic solvent.
