ABSTRACT:
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them at dehydrogenation conditions with a nonacidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, a tin or lead 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 component, an iridium component, a tin or lead 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 2 wt. % iridium, 0.01 to 5 wt. % tin or lead, and 0.1 to 5 wt. % of the alkali or alkaline earth metal.
