Abstract
An improved catalyst of platinum, rhenium and tin with an inert support used for hydrogenation of an hydrogenatable precursor in an aqueous solution and a method for using the catalyst in the production of tetrahydrofuran and 1,4-butanediol from such a hydrogenatable precursor in an aqueous solution.
Claims12
A hydrogenation catalyst comprising about 0.5% to 3% platinum, about 1% to 10% rhenium and about 0.1% to about 5% tin supported on carbon, wherein the percentages are by total weight of the supported catalyst.
A method for making tetrahydrofuran, 1,4-butanediol or mixtures thereof by hydrogenating a hydrogenatable precursor in a reactor in the presence of a catalyst comprising about 0.5% to 3% platinum, about 1% to 10% rhenium and about 0.1% to 5% tin, supported on carbon, wherein the percentages are by total weight of supported catalyst.
