ABSTRACT:
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a selectively sulfided acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a tin component, a sulfided nickel component, and a halogen component with a porous carrier material. The platinum group component, tin component, sulfided nickel component, and halogen component are present in the multimetallic 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. % tin, about 0.01 to about 5 wt. % nickel, and about 0.1 to about 3.5 wt. % halogen. These metallic components are, moreover, relatively 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, substantially all of the catalytically available nickel component is present in a sulfided state, while substantially all of the tin is present therein in the form of tin oxide. 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 a hydrogen stream are contacted with the selectively sulfided acidic multimetallic catalyst disclosed herein at reforming conditions.
