ABSTRACT:
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them at dehydrogenation conditions, with a sulfided catalytic composite comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, and a nickel component with a porous carrier material. A specific example of the sulfided nonacidic catalytic composite disclosed herein is a combination of a platinum or palladium component, an iridium component, a nickel component, an alkali or alkaline earth component and a sulfur component with a porous carrier material; wherein the metallic components are uniformly dispersed throughout the porous carrier material; wherein substantially all of the platinum or palladium, iridium and nickel components are present therein in the elemental metallic state or in a sulfided state or in a mixture thereof; wherein substantially all of the alkali or alkaline earth component is present therein in an oxidation state above the elemental metal; wherein the composite contains, on an elemental basis, about 0.01 to about 2 wt. % platinum or palladium, about 0.01 to about 2 wt. % iridium, about 0.1 to about 5 wt. % alkali metal or alkaline earth metal, about 0.01 to about 5 wt. % nickel and about 0.01 to about 1 wt. % sulfur; and wherein the composite is sulfided prior to use in the dehydrogenation method and after the metallic components thereof have been reduced to the elemental metallic state.
