HYDROGENATION CATALYSTS PREPARED FROM POLYOXOMETALATE PRECURSORS AND PROCESS FOR USING SAME TO PRODUCE ETHANOL

摘要

The present invention relates to hydrogenation catalysts prepared from polyoxometalate precursors. The polyoxometalate precursors introduce a support modifier to the catalyst. The catalysts are used for hydrogenating alkanoic acids and/or esters thereof to alcohols, preferably with conversion of the ester coproduct. The catalyst may also comprise one or more active metals.
