Abstract
A supported catalyst composition, which is effective as a diolefin hydrogenation catalyst, comprises palladium, silver and alkali metal fluoride. This catalyst composition is employed in the selective hydrogenation of C.sub.4 -C.sub.10 diolefins (preferably 1,3-butadiene) with hydrogen gas to the corresponding monoolefins.
