ABSTRACT:
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel superactive multimetallic catalytic composite comprising a reduced combination of a catalytically effective amount of an adsorbed rhenium-oxygen complex with a porous carrier material containing a catalytically effective amount of a conventional rhenium component and a uniform dispersion of a catalytically effective amount of a platinum group component which is maintained in the elemental metallic state during the adsorption and reduction of the rhenium-oxygen complex. A key feature associated with the preparation of the subject catalytic composite is reaction of a rhenium-oxygen complex with a porous carrier material containing a conventional rhenium component and a uniform dispersion of a platinum group component maintained in the elemental state, whereby the interaction of the rhenium-oxygen complex with the platinum group metal moiety is maximized due to the platinophilic (i.e. platinum-seeking) propensities of the oxygen ligands used in the rhenium 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 superactive multimetallic catalytic composite at reforming conditions.
