Patent ID: 7297824

Claim:
The method of selectively hydrogenating acetylenic compounds comprising contacting a feed containing acetylenic compounds and other unsaturated compounds with a catalyst consisting of about 9.67 to about 20 wt. % Ni and one or more elements selected from the group consisting of from about 0.1 to about 10 wt. % Zn, from about 0.1 to about 7 wt. % Mg, and from about 0.1 to about 7 wt. % Ca deposited on an alumina support having the following physical properties: BET surface area of from 30 to about 100 m 2 /g, total nitrogen pore volume of from 0.4 to about 0.9 cc/g, and an average pore diameter of from about 110 to 450, at least 50% of the pores larger than 100 Å diameter, and a total pore volume from about 0.405 cc/g to about 0.9 cc/g and ABD (apparent bulk density) from about 0.35 to about 0.75 g/cc Å under selective hydrogenation conditions and recovering a product having less acetylenic compounds than said feed.
