Process for removing intermittent organic compounds from gaseous streams

摘要

Intermittent hydrocarbon contaminants, which are volatilized by an air regeneration stream from coked catalyst in cyclic dehydrogenation process, are effectively removed from the gaseous regeneration stream containing them prior to venting it by contacting that portion of the stream containing a predominant 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 contaminants to water and CO2.
