Hydrocarbon conversion with an acidic trimetallic catalytic composite

Abstract

Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic trimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a Group IV-A metallic component, a Group VI-B transition metal component and a halogen component with a porous carrier material. The platinum group component, Group IV-A metallic component, and halogen component are present in the trimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % Group IV-A metal and about 0.1 to about 3.5 wt. % halogen. The Group VI-B component is present in an amount of about 0.01 to about 3 wt. % and the atomic ratio of Group VI-B metal to platinum group metal is about 0.05:1 to about 4:1. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group metal is present therein in the elemental metallic state; while substantially all of the Group IV-A metallic component and all of the Group VI-B component are present therein in an oxidation state above that of the corresponding metal.
