Abstract
By this invention there is provided a catalyst composition comprising a Group IVB oxide, an amorphous silica-alumina support having dispersed thereon a rare earth oxide, which as herein used also includes yttrium oxide, and a metal(s) selected from the group consisting of Group VIII noble metal(s), mixtures of Group VIII noble metal(s) and tin, mixtures of Group VIII noble metal(s) and rhenium, and mixtures of Group VIII noble metal(s), tin and rhenium. The amorphous silica-alumina support contains at least about 50% silica by weight. The catalyst can function as a hydrocarbon conversion catalyst in reactions where platinum on halided (Cl,F)-alumina is typically used.
