ABSTRACT:
C.sub.2 -C.sub.6 alkynes (preferably acetylene) contained in feeds which also contain sulfur impurities are hydrogenated to the corresponding alkenes in the presence of a supported palladium catalyst which has been promoted with alkali metal fluoride (preferably potassium fluoride). A specific cataylst consists essentially of a palladium component, at least one alkali metal fluoride (preferably KF) and an inorganic support material (preferably alumina).
