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 sulfided rhenium component and a halogen component with a porous carrier material formed from Ziegler alumina. The platinum group component, sulfided rhenium component, and halogen component are present in the multimetallic catalytic composite in proportions of 0.01 to 2 wt. % rhenium, 0.1 to 3.5 wt. % halogen and sulfur in an amount at least sufficient to provide an atomic ratio of sulfur to rhenium of at least about 0.5:1. These metallic components are dispersed throughout the Ziegler alumina carrier material in carefully controlled oxidation state such that substantially all of the platinum group metal is present therein in the elemental metallic state and a substantial portion of the rhenium present therein is maintained in a sulfided state. A key feature of the hydrocarbon conversion process using the subject catalyst involves the continuous maintenance of the sulfided state of the rhenium component for the duration of the hydrocarbon conversion process. A specific example 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 instant selectively sulfided acidic multimetallic catalyst at reforming conditions.
