摘要： The presently disclosed subject matter relates to methods and systems for alkane dehydrogenation. In a particular non-limiting embodiment, the presently disclosed subject matter provides a system for the dehydrogenation of alkanes that includes two or more reactors configured to perform a dehydrogenation reaction of an alkane in the presence of a catalyst to produce an olefin and a catalyst regenerator, coupled to each of the two or more reactors through at least one transfer line to a regenerator, for the regeneration of spent catalyst.

摘要： The present disclosure addresses the deficiencies described above by providing systems and methods for enhancing the efficiency and yield of alkene production. The methods and systems provide for the use of activated CO2 in a dehydrogenation reactor along with an alkane stream. Through the use of the methods and systems of the invention, catalyst deactivation by coke deposition is reduced and the selectivity and efficiency of the dehydrogenation reaction is improved.
