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 50 and preferably 70 weight percent of the copper metal and the activator metal are dispersed on the outer 200 micron layer of the support.
Claims7
A process for selectively hydrogenating C4-acetylenes in a liquid hydrocarbon stream containing largely butadiene comprising contacting hydrogen and the hydrocarbon stream with a catalytic composite comprising an inorganic oxide support having dispersed thereon finely divided copper metal and an activator metal selected from the group consisting of nickel, cobalt, platinum, palladium, manganese, and a combination thereof where said copper metal and said activator metal are dispersed on said support using impregnation where the volume of the impregnating solution is less than that required to fill the pore volume resulting in at least 50 weight percent of said copper metal and said activator metal being dispersed on the outer 200 micron layer of the support.
A process for selectively hydrogenating C4-acetylenes in a liquid hydrocarbon stream containing largely butadiene comprising contacting hydrogen and the hydrocarbon stream with a catalytic composite comprising an inorganic oxide support having dispersed thereon finely divided copper metal and optionally an activator metal selected from the group consisting of nickel, cobalt, platinum, palladium, manganese, and a combination thereof where said copper metal and said activator metal are dispersed on said support using impregnation where the volume of the impregnating solution is less than that required to fill the pore volume resulting in at least 70 weight percent of said copper metal and said activator metal being dispersed on the outer 200 micron layer of the support.
