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, an iridium component, a rhenium 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, an iridium component, a rhenium 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, the iridium component and the rhenium component are present as the corresponding elemental metals and substantially all of the tin component is present 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. % iridium, about 0.01 to about 2 wt. % rhenium, about 0.01 to about 5 wt. % tin and about 0.01 to about 5 wt. % alkali or alkaline earth metal.
