    摘要: A process for preparing a bimetallic catalyst useful for the hydrodechlorination of chlorinated hydrocarbons, comprising impregnating a support with an active hydrogenating metal from a salt solution of the metal, recovering and drying the thus-impregnated support, reducing the impregnated support by exposure to hydrogen and oxidizing the active hydrogenating metal on said support to an oxidized state by exposure to an oxidizing environment, then impregnating the thus-treated support with a surface segregating metal from a salt solution thereof, aging the support/salt solution mixture over a period of time at an elevated temperature, and finally cooling, recovering and drying the catalyst before charging the same to a reactor for reduction or reduction and chloride source pretreatment and subsequent use.

    摘要: Dehydrocyclizable hydrocarbons are converted to aromatics by contacting them at dehydrocyclization conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum or palladium component, a rhodium component, a cobalt component, and a halogen component with a porous carrier material. In a preferred embodiment, the catalytic composite also contains a catalytically effective amount of a Group IVA metallic component. The platinum or palladium, rhodium, cobalt and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum or palladium metal, about 0.01 to about 2 wt. % rhodium, about 0.05 to about 5 wt. % cobalt, and about 0.1 to about 3.5 wt % halogen. Moreover, the catalytically active sites induced by these metallic components are uniformly dispersed throughout the porous carrier material and these metallic components are present in the catalyst in carefully controlled oxidation states. A specific example of the dehydrocyclization method disclosed herein is a method for converting a feed mixture of n-hexane and n-heptane to a product mixture of benzene and toluene which involves contacting the feed mixture and a hydrogen stream with the acidic multimetallic catalyst disclosed herein at dehydrocyclization conditions.
