Hydrocarbon conversion with a multimetallic catalytic composite

Abstract

Abstract Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a trimetallic acidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a Group IVA metallic component, a Group VIB transition metal component and a halogen component with a porous carrier material. The platinum group component, Group IVA 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 IVA metal and about 0.1 to about 3.5 wt. % halogen. The Group VIB component is present in an amount of about 0.01 to about 3 wt. % and the atomic ratio of Group VIB 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 IVA metallic component and of the Group VIB component are present therein in oxidation states above that of the corresponding metal. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and hydrogen stream are contacted with the novel trimetallic catalyst disclosed herein at reforming conditions.
