Claim:
A method of making a promoted catalyst for selective hydrogenation comprising: impregnating a carrier by incipient wetness impregnation with an aqueous solution of a promoter selected from the group consisting of Group IB metals, Group IIB metals, Group IIIA metals, Group VIIB metals, and combinations thereof, in a concentration sufficient to deposit the promoter on the carrier in a finished concentration of from about 0.05 wt-% to about 1.0 wt-%; drying the product of the impregnation for about one hour at about 150° C.; calcining the dried product at about 300° C.; reducing the calcined product for 1-2 hours at a temperature in the range of from about 100° C. to about 425° C. in an atmosphere consisting of an approximately 2:1 mixture of H 2 :CO at a pressure of from about 150 psig to about 250 psig.
