FIELD: hydrogenation-dehydrogenation catalysts and processes. SUBSTANCE: invention provides hydrogenation catalyst to hydrogenate more unsaturated hydrocarbon, such as alkyne or diene, into less unsaturated ones, such as alkene or olefin. Catalyst contains palladium, silver, and spinel, each of them being present in proportion high enough to influence hydrogenation of unsaturated hydrocarbon. Palladium is optionally present as shell distributed across the surface of spinel. Hydrogenation process involving such catalyst is also described. EFFECT: increased selectivity and prolonged lifetime. 8 cl, 9 tbl, 8 ex |
