ABSTRACT:
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions including a hydrogen-rich and substantially water-free environment, with a catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a Group IVA metallic component, and a lanthanide series component with a porous carrier material. A specific example of the catalyst used in the disclosed hydrocarbon dehydrogenation method in a nonacidic catalytic composite comprising a combination of a platinum group component, a Group IVA metallic component, a lanthanide series component, and an alkali or alkaline earth component with a porous carrier material in amounts sufficient to result in a composite containing about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % Group IVA metal, about 0.1 to about 5 wt. % alkali metal or alkaline earth metal, and having an atomic ratio of lanthanide series metal to platinum group metal of about 0.1:1 to 1.25:1. A preferred modifying component for the disclosed catalytic composites in a sulfiding reagent.
