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 nickel component, and a zinc 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 nickel component, a zinc 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. % nickel, about 0.01 to about 5 wt. % zinc, and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.
Claims9
A nonacidic catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 wt. % platinum group metal, about 0.05 to about 5 wt. % nickel, about 0.1 to about 5 wt. % alkali metal or alkaline earth metal, and about 0.01 to about 5 wt. % zinc;
- wherein the platinum group, catalytically available nickel, zinc and alkali or alkaline earth components are uniformly dispersed throughout the porous carrier material;
- wherein substantially all of the platinum group component is present in the elemental metallic state;
- wherein 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 dehydrogenation conditions or in a mixture of these states;
- and wherein substantially all of the alkali or alkaline earth component is present in a positive oxidation state.
