Abstract: PROBLEM TO BE SOLVED: To provide a catalyst highly active and highly selective even at low working temperature by depositing a prescribed thickness and amount of palladium as a sol on a carrier by impregnation or successive spraying and heating processes. SOLUTION: A palladium sol is previously produced and then the palladium sol is sprayed to a heated carrier of an inorganic oxide such as alumina and the likes or the carrier is immersed in the palladium sol. Consequently, a palladium-carrier catalyst is obtained and the catalyst contains palladium in 0.001-2 wt.% content existing in a layer having a thickness of less than 5000 nm forming a shell around the carrier, substantially in the absence of a promoter metal. The catalyst is highly active and highly selective even at low temperature and without requiring an adjusting agent such CO, the catalyst enables hydrogenation of acetylene in C2 -flow and promotes selective hydrogenation of acetylene and diene in gas phase.
