Catalyst composition useful for hydrogenation of alkynes

A catalyst composition comprises palladium, at least one chemically bound alkali metal (preferably potassium), chemically bound fluorine and an inorganic support material (preferably alumina), wherein the atomic ratio of fluorine to alkali metals about 1.3:1 to about 4:1. Preferably, silver is also...

More Information
Summary:A catalyst composition comprises palladium, at least one chemically bound alkali metal (preferably potassium), chemically bound fluorine and an inorganic support material (preferably alumina), wherein the atomic ratio of fluorine to alkali metals about 1.3:1 to about 4:1. Preferably, silver is also present in the catalyst composition. The above-described catalyst is employed as a catalyst in the selective hydrogenation of C2-C10 alkynes (preferably acetylene) to the corresponding alkenes in the presence of sulfur impurities.
