Abstract
A process is described for producing furan from furfural from biomass, wherein furfural in an aqueous mass or stream from the liquefaction of biomass or a biomass fraction including one or more furfural precursors is extracted into an organic solvent which is readily separable from furan by simple distillation at atmospheric pressure, furfural is catalytically decarbonylated to furan in the organic solvent and furan is separated from the organic solvent by simple distillation. The furan from the distillation step may be hydrogenated to provide tetrahydrofuran.
