Abstract
Abstract A nonacidic catalytic composite especially useful for dehydrogenating dehydrogenatable hydrocarbons comprises a combination of a platinum group component, a cobalt component, a zinc 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. % zinc and about 0.1 to about 5 wt. % alkali metal or alkaline earth metal.
