<p>A catalyst composition comprising an inorganic support material, a palladium component, a silver component, and a promotor component having the formula XYFn, wherein X is an alkaline metal, Y is an element selected from the group consisting an antimony, phosphorus, boron. Aluminum, gallium, indium, thallium, and arsenic, and n is an integer which makes YFn a monovalent anion. The above-described catalyst is employed as a catalyst in the selective hydrogenation of acetylene. The above-described catalyst is made by incorporating a palladium component, a silver component, and a promoter component into an inorganic support material.</p> |
