ABSTRACT:
A dehydrogenatable hydrocarbon is dehydrogenated by contacting the hydrocarbon, hydrogen, and water or a water-producing substance, at dehydrogenation conditions, with a nonacidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group metal component, a nickel component, a Group IVA metallic component, and an alkali or alkaline earth component with a porous carrier material. A specific example of the nonacidic, multimetallic catalytic composite disclosed herein is a combination of a platinum metal component, a nickel component, a germanium component, and an alkali or alkaline earth component with an alumina carrier material. The amounts of the catalytically active components contained in this last composite are, on an elemental basis, 0.01 to 2 wt. % platinum, 0.01 to 5 wt. % nickel, 0.01 to 5 wt. % germanium, and 0.1 to 5 wt. % of the alkali or alkaline earth metal.
