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.
Claims20
A process for selectively hydrogenating diolefins containing 4-10 carbon atoms per molecule with hydrogen gas to monoolefins containing 4-10 carbon atoms per molecule, wherein the improvement comprises employing a catalyst composition comprising (a) at least one palladium-containing material selected from the group consisting of palladium metal and palladium oxide, (b) at least one silver-containing material selected from the group consisting of silver metal and silver oxide, (c) at least one alkali metal fluoride, and (d) at least one inorganic support material,
- wherein said catalyst composition comprises about 0.01-2 weight-%. palladium, about 0.02-10 weight-% silver, and about 0.05-10 weight-% alkali metal.
