ABSTRACT:
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.
