    摘要: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel attenuated superactive multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed rhenium carbonylcomponent 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 rhenium carbonyl component, and of a tin 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 rhenium carbonyl component, tin 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. % platinum group metal, about 0.01 to about 5 wt. % rhenium, about 0.005 to about 5 wt. % tin and about 0.1 to about 3.5 wt. % halogen. A key feature associated with the preparation of the subject catalytic composite is reaction of a rhenium carbonyl complex with a porous carrier material containing a uniform dispersion of a tin component and of a platinum group component maintained in the elemental state, whereby the interaction of the rhenium moiety with the platinum group moiety is maximized due to the platinophilic (i.e. platinum-seeking) propensities of the carbon monoxide ligands associated with 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 attenuated superactive multimetallic catalytic composite at reforming conditions.

    摘要: 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.
