Process for dehydrogenating hydrocarbons

摘要

A continuous process for dehydrogenating hydrocarbons comprising repetitively carrying out dehydrogenation using a steam active dehydrogenation catalyst and regenerating of said catalyst with steam and oxygen-containing gas wherein the flow rate of steam is maintained constant during both the dehydrogenation and the regeneration and wherein the catalyst is purged with steam prior to each dehydrogenation and each regeneration.
