Patent ID: 7745370

Claim:
A method for the manufacture of a catalyst for the selective hydrogenation of acetylene and diolefins comprising: a) preparing a carrier having a low surface area of about 2 m 2 /g to about 20 m 2 /g and having a pore volume of greater than about 0.4 cc/g, wherein at least 90% of the pore volume is contained in pores having a pore diameter greater than about 500 Å and about 1% to about 2% of the pore volume is contained in pores having a pore diameter of about 500 Å to about 1,000 Å, b) impregnating the carrier with a palladium metal source, c) reducing the palladium impregnated catalyst, d) washing and drying the reduced palladium catalyst, e) impregnating the catalyst with a Group IB metal additive source, f) reducing the Group IB metal additive source, and g) washing and drying the reduced catalyst to form a catalyst for use in the selective hydrogenation of acetylene and diolefins.
