Abstract: The present invention provides a process for the production of THF and 1,4-BDO from furan in the presence of a catalytic composition, wherein the catalytic composition contains at least one metal selected from the group consisting of Fe, Ru, Os, Co, Rh, Jr, Ni, Pd, Pt and, optionally, contains one or more additional metal on a solid support, and wherein said process comprises the steps of: i) contacting furan with hydrogen and water in a reactor in the presence of said catalytic composition for a time; ii) stopping the flow of furan and the flow of water to the reactor and removing furan and water from the reactor; iii) subjecting the catalytic composition to a gas stream comprising hydrogen at a temperature of from 200 to 600° C. in the absence of the furan and water; iv) re-starting the flow of furan and the flow of water to the reactor.

Abstract: The present invention provides a method for increasing the molar ratio of tetrahydrofuran to 1,4-butanediol in a process for the production of 1,4-butanediol and tetrahydrofuran, said process comprising contacting furan with hydrogen and water in a reactor vessel at an initial partial pressure of hydrogen, and in the presence of a catalytic composition comprising at least one metal on a solid support, wherein the at least one metal is selected from cobalt, nickel, ruthenium, palladium and platinum and wherein the molar ratio of tetrahydrofuran to 1,4-butanediol is increased by increasing the partial pressure of hydrogen in the reactor vessel above the initial partial pressure of hydrogen.
