    摘要: A catalyst for selective hydrogenation of acetylenes and diolefins, particularly in a raw gas feed stream for front end selective hydrogenation. The catalyst contains a low surface area carrier with a surface area from about 2-20 m2/g, wherein the pore volume of the pores of the carrier is greater than about 0.4 cc/g, wherein at least 90 percent of the pore volume of the pores is contained within pores having a pore diameter greater than about 500 Å and wherein from about 1 to about 2 percent of the total pore volume is contained in pores with a pore diameter from about 500 to about 1,000 Å, palladium, wherein the palladium comprises from about 0.01 to about 0.1 weight percent of the catalyst, and a Group IB metal, wherein the Group IB metal comprises from about 0.005 to about 0.06 weight percent of the catalyst.
