ABSTRACT:
This invention relates to a catalyst containing palladium and optionally chromium on an alumina which is used for the selective hydrogenation of acetylenic hydrocarbons in olefin gas streams. The catalyst is characterized by the use of an alumina support having a surface area of less than about 5 square meters per gram, a Hg pore volume of between about 0.2 and about 0.5 cubic centimeters per gram and wherein at least 40% of the pore volume is contained in pores having pore diameters of greater than about 10 microns.
