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 tin component with a porous carrier material. A specific example of the catalytic composite disclosed herein is a combination of a platinum or palladium component, a rhodium component, a tin component, and an alkali or alkaline earth component with a porous carrier material wherein substantially all of the platinum or palladium component and the rhodium component are present therein as the corresponding elemental metals and substantially all of the tin component and the alkali or alkaline earth component are present therein in an oxidation state above the elemental metal, and wherein the composite contains about 0.01 to about 2 wt. % platinum or palladium, about 0.01 to about 2 wt. % rhodium, about 0.01 to about 5 wt. % tin, and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.
