Abstract
A process for selectively hydrogenating C4-acetylenes in a liquid hydrocarbon stream containing largely butadiene has been developed. Hydrogen and the hydrocarbon stream are contacted with a catalytic composite comprising an inorganic oxide support having dispersed thereon finely divided copper metal and an activator metal of nickel, cobalt, platinum, palladium, manganese, or a combination thereof where 1) the catalytic composite has an average diameter of up to about {fraction (1/32)} inch (800 microns) and/or 2) at least 70 weight percent of the copper metal and the activator metal are dispersed on the outer 200 micron layer of the support.
