ABSTRACT:
This invention relates to a new process for dehydrogenating hydrocarbons utilizing a catalyst comprising a platinum group component, an alkali or alkaline earth component and a porous support material. After the catalyst is used to dehydrogenate hydrocarbons it is contacted in a catalyst regeneration zone with a halogen component to produce a regenerated catalyst containing added halogen component, which regenerated catalyst can then be reused to dehydrogenate hydrocarbons. The added halogen component increases the catalyst's activity and stability in the dehydrogenation process.
