Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel activated multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed ruthenium carbonyl component with a porous carrier material containing a uniform dispersion of a catalytically effective amount of a platinum group component, which is maintained in the elemental metallic state during the incorporation and pyrolysis of the ruthenium carbonyl component, and of a rhenium component. In a highly preferred embodiment, this novel catalytic composite also contains a catalytically effective amount of a halogen component. The platinum group component, pyrolyzed ruthenium carbonyl component, rhenium component and optional halogen component are preferably present in the multimetallic catalytic composite in amounts, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % of the uniformly dispersed platinum group metal, about 0.01 to about 2 wt. % of carbonyl-derived ruthenium, about 0.01 to about 5 wt. % rhenium and about 0.01 to about 3.5 wt. % of halogen. Key feature associated with the preparation of the subject catalytic composite is reaction of a ruthenium carbonyl complex with a porous carrier material containing a uniform dispersion of a rhenium component and of a platinum group component maintained in the elemental state, whereby the interaction of the ruthenium moiety with the platinum group moiety is maximized due to the platinophilic (I.E. Platinum-seeking) propensities of the carbon monoxide ligand used in the ruthenium reagent. A specific example of the type of hydrocarbon conversion process disclosed herein 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 subject activated multimetallic catalytic composite at reforming conditions.
