ABSTRACT:
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum or palladium component, a rhodium component, an indium component, and a halogen component with a porous carrier material. The platinum or palladium, rhodium, indium, and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt.% platinum or palladium metal, about 0.01 to about 2 wt.% rhodium, about 0.01 to about 1 wt.% indium, and about 0.1 to about 3.5 wt.% halogen. Moreover, the catalytically active sites induced by these metallic components are uniformly dispersed throughout the porous carrier material and these components are present herein in carefully controlled oxidation states such that substantially all of the platinum or palladium and rhodium components are in the elemental metallic state and substantialy all of the indium is in an oxidation state above that of the elemental 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 a hydrogen stream are contacted with the acidic multimetallic catalyst disclosed herein at reforming conditions.
