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 4):
The process of  claim 3 , wherein the catalytic conversion step is selected from the group consisting of: hydrogenolysis, pyrolysis, base hydrolysis, and a hydrodeoxygenation reaction.
