PROCESS FOR THE HYDROGENATION OF AROMATICS

摘要

The present invention pertains to a process for effecting aromatics hydrogenation which process comprises contacting a hydrocarbon feedstock which contains 10-80 vol.% of aromatics in the presence of a hydrogen-containing gas with a catalyst which comprises hydrogenation metals on a carrier. Wherein (i) the hydrogenation metals comprise a combination of platinum and palladium, and (ii) the carrier comprises silica-alumina dispersed in an alumina binder, wherein the alumina binder is present in an amount of 5-50 wt.%, based on the total weight of the silica-alumina and alumina binder present in the carrier, and wherein the silica-alumina comprises 5-50 wt.% of alumina, based on the weight of the silica-alumina. The use of a catalyst comprising platinum and palladium on a carrier comprising silica-alumina and 5-50 wt.% of an alumina binder, the silica-alumina comprising 5-50 wt.% of alumina, based on the weight of the silica-alumina, leads to an increased aromatics hydrogenation as compared to a catalyst containing only platinum as hydrogenation metal, and as compared to a catalyst containing more than 50 wt.% of an alumina binder and/or more than 50 wt.% of alumina in the silica-alumina contained in the carrier.
