Abstract of the Disclosure A catalyst for the hydrogenation of alkynes has a gamma alumina support carrying copper metal and optionally an activator metal. The catalysts of the invention have surprising high selectivity for alkynes, to the relative exclusion of alkenes. The catalyst are advantageously employed for the removal of alkynes (such as 1-butyne-3-ene) from a diene (such as 1,3-butadiene) with relatively little degradation of the diene.
