Abstract: A process for converting polyhydric alcohols to monoalcohols in a counter current column reactor with a metal based catalyst supported on a porous membrane coated over a tubular system that delivers hydrogen where a hydrocarbon (low polarity) liquid solvent is fed at the bottom of the column reactor and an aqueous liquid having polyhydric alcohols therein is fed into the top of the reactor such that the aqueous liquid flows countercurrent to the low polarity solvent liquid and further wherein the low polarity solvent liquid is less dense than the aqueous liquid such that the two liquids are subject to phase separation. Monoalcohols are formed by hydrogenolysis reactions of polyhydric alcohols on the metal catalyst. Monoalcohols phase separate from the aqueous phase to the hydrocarbon solvent. Monoalcohols are further separated from the organic solvent.
