Appl. No.:

6/047605

Inventors:

John F. Flagg - Rosemont IL
George J. Antos - Bartlett IL

Abstract:

An acidic multimetallic catalytic composite especially useful for converting hydrocarbons comprises a combination of catalytically effective amounts of a platinum group component, a nickel component, a uranium component, and a halogen component with a porous carrier material. The platinum group, uranium, nickel, 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 group metal, about 0. 1 to about 10 wt. % uranium, about 0. 05 to about 5 wt. % nickel, and about 0. 1 to about 3. 5 wt. % halogen. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group component is present therein in the elemental metallic state, substantially all of the catalytically available nickel component is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions, or in a mixture of these states, while substantially all of the uranium component is present in an oxidation state above that of the elemental metal.

Abstract:

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 group component, a cobalt component, a uranium component, and a halogen component with a porous carrier material. The platinum group, cobalt, uranium 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 group metal, about 0. 05 to about 5 wt. % cobalt, about 0. 1 to about 10 wt. % uranium, 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 such that substantially all of the platinum group component is in the elemental metallic state, substantially all of the uranium component is in an oxidation state above that of the elemental metal, and substantially all of the catalytically available cobalt component is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under dehydrocyclization conditions, or in a mixture of these states. A specific example of 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.

Abstract:

Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions, with a catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a cobalt component, and a uranium component with a porous carrier material. A specific example of the nonacidic catalytic composite disclosed herein is a combination of a platinum group component, a cobalt component, a uranium component, and an alkali or alkaline earth component with a porous carrier material in amounts sufficient to result in a composite containing about 0. 01 to about 2 wt. % platinum group metal, about 0. 05 to about 5 wt. % cobalt, about 0. 1 to about 10 wt. % uranium and about 0. 1 to about 5 wt.

Abstract:

Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a uranium component, a cobalt component, and a halogen component with a porous carrier material. The platinum group, uranium, cobalt and halogen components are present in the multimetallic catalyst in amounts repectively, calculated on an elemental basis, corresponding to about 0. 01 to about 2 wt. % platinum group metal, about 0. 1 to about 10 wt. % uranium, about 0. 05 to about 5 wt. % cobalt, and about 0. 1 to about 3. 5 wt. % halogen. These metallic components are, moreover, uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group metal is present therein in the elemental metallic state, substantially all of the catalytically available cobalt component is present therein in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions, or in a mixture of these states, while substantially all of the uranium is present therein in an oxidation state above that of the elemental metal. A specific example of the type of hydrocarbon conversion process disclosed 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 acidic multimetallic catalyst disclosed herein at reforming conditions.
