Abstract
A nonacidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a cobalt component, a tantalum component, and an alkali or alkaline earth component with a porous carrier material is disclosed. A specific example of the composite is one containing about 0.01 to about 2 wt. % platinum group metal, about 0.05 to about 5 wt. % cobalt component, about 0.01 to about 5 wt. % tantalum component, and about 0.1 to about 5 wt. % alkali or alkaline earth component.
Claims8
A nonacidic catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 wt.% platinum group component, about 0.05 to about 5 wt.% cobalt component, and 0.01 to about 5 wt.% tantalum component, and about 0.1 to about 5 wt.% alkali or alkaline earth component;
- wherein the platinum group, catalytically available cobalt, tantalum 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 cobalt 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;
- wherein substantially all of the tantalum component is present in a positive oxidation state;
- and wherein substantially all of the alkali or alkaline earth component is present in a positive oxidation state.
