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 or palladium component, a rhodium component and a cobalt component with a porous carrier material. A specific example of the nonacidic catalytic composite disclosed herein is a combination of a platinum or palladium component, a rhodium component, a cobalt 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 or palladium, about 0.01 to about 2 wt. % rhodium, about 0.05 to about 5 wt. % cobalt and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal. A preferred modifying component for the disclosed catalytic composites is a Group IVA metallic component.
