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, a rhenium component, a germanium component, and a halogen component with a porous carrier material. The platinum or palladium, rhodium, rhenium, germanium, and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on a finished catalyst and 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 2 wt. % rhenium, about 0.01 to about 5 wt. % germanium, and about 0.1 to about 3.5 wt. % halogen. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum or palladium, rhenium and rhodium components are present therein in the elemental metallic state, and substantially all of the germanium component is present in an oxidation state above that of the elemental metal.
