View the Complete Application at the US Patent & Trademark Office
The present invention relates to an integrated multi-zone process for conversion of alkanes to their corresponding alkenes, involving exothermically converting a portion of an alkane to its corresponding alkene by oxidative dehydrogenation in an exothermic reaction zone, in the presence of oxygen and a suitable catalyst, and then feeding the products of the exothermic reaction zone to an endothermic reaction zone wherein at least a portion of the remaining unconverted alkane is endothermically dehydrogenated, in the presence of carbon dioxide and an other suitable catalyst.
