Abstract (en)

[origin: WO2004004901A1] A process for selectively hydrogenating C>4<-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 800 mu m (1/32 inch) and/or 2) at least 70 weight percent of the copper metal and the activator metal are dispersed on the outer 200 mu m layer of the support.
