ABSTRACT:
Naphthene hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions, with a catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a cobalt component, and a bismuth component with a porous carrier material. A specific example of the preferred nonacidic catalytic composite for use in this dehydrogenation method is a combination of a platinum group component, a cobalt component, a bismuth 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 0.05 to about 5 wt. % cobalt, about 0.01 to about 5 wt. % bismuth and about 0.1 to about 5 wt. & alkali metal or alkaline earth metal.
