Abstract:
A process for the selective hydrogenation of acetylenes comprising contacting a feed containing acetylenes in at least partial liquid phase with a catalyst comprising a copper component and a member selected from the group consisting of at least one Group VIII metal component, a Ag component, a Au component and mixtures thereof on an alumina support having apparent bulk density of less than about 0.70 g/cm3, no pores less than about 30 Ã¥ diameter, about 90% of pores having pore diameter larger than 100 Ã¥ determined by nitrogen porosimetry, BET surface area of 30 to less than about 230 m2/g and total pore volume larger than about 0.65 cc/g under conditions to selectively hydrogenate said acetylenes.
