A process of catalytically dehydrogenating an alkane to an alkene, using CrOas a catalyst, where the catalyst is oxidized to CrOduring the dehydrogenation, and is regenerated by using CO as a reducing gas. In regenerating the catalyst with CO, COis produced, which may be fed to a dehydrogenation reactor with the alkane and reacted with Hproduced by the dehydrogenation, to form CO and HO by the reverse water-gas shift reaction.

Process for enhancing the performance of the dehydrogenation of alkanes

A process of catalytically dehydrogenating an alkane to an alkene, using CrOas a catalyst, where the catalyst is reduced concurrently with the dehydrogenation by using CO as a reducing gas. In reducing the catalyst with CO, COis produced, which may be reacted with Hproduced by the dehydrogenation, to form CO and HO by the reverse water-gas shift reaction. A Cu O heat-releasing material may be included with the catalyst in the reactor. The CO reducing gas reduces CuO to form Cu and CO, releasing heat. The COproduced by reducing the Cu O may also be reacted with Hproduced by the dehydrogenation, to form CO and HO by the reverse water-gas shift reaction.
