| 摘要 |
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel sulfided and attenuated superactive multimetallic catalytic composite comprising a sulfided combination of a catalytically effective amount of a pyrolyzed rhenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component, which is maintained in the elemental metallic state during the incorporation of the rhenium carbonyl component, and of a zinc component. 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 sulfided and attenuated superactive multimetallic catalytic composite at reforming conditions.
