ABSTRACT:
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions, with a nonacidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a rhenium component, a cobalt component, a tin component and an alkali or alkaline earth component with a porous carrier material. A specific example of the nonacidic catalytic composite disclosed herein is a combination of a platinum group metal, rhenium, cobalt, tin and an alkali or alkaline earth metal with a porous carrier material in amounts sufficient to result in a composite containing, on an elemental basis, about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 2 wt. % rhenium, about 0.05 to about 5 wt. % cobalt, about 0.01 to about 5 wt. % tin and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.
