ABSTRACT:
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them at hydrocarbon dehydrogenation conditions with a multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed ruthenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component maintained in the elemental metallic state, and of a rhenium component. An optional non-acidic multimetallic catalytic composite disclosed herein is a combination of a catalytically effective amount of a pyrolyzed ruthenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component which is maintained in the elemental metallic state during the incorporation of the ruthenium carbonyl component, a rhenium component, and an alkali or alkaline earth component.
