ABSTRACT:
Intermittant hydrocarbon contaminates, which are volatilized by an air regeneration stream from coked catalyst in cyclic dehydrogenation processes, are effectively removed from the gaseous regeneration stream containing them prior to venting it by contacting that portion of the stream containing a predominate amount of the volatilized hydrocarbons with a catalyst such as chromia-alumina in the presence of air to convert a substantial amount of the hydrocarbon contaminates to water and CO.sub.2.
