Abstract

The present invention relates to an integrated multi-zone process for the conversion of alkanes to their corresponding alkenes comprising the exothermic conversion of a portion of the alkanes by oxidative dehydrogenation in an exothermic reaction zone in the presence of oxygen and a suitable catalyst to its corresponding alkenes, the product of said exothermic reaction zone is then passed to an endothermic reactor in which at least a portion of the remaining unconverted alkanes are absorbed in the presence of carbon dioxide and other suitable catalysts Thermal dehydrogenation.

Description

[0001] Government rights

[0002] The present invention was made in accordance with the document No. DE-FC36-04G014272 issued by the US Department of Energy with the support of the US government. The U.S. government has certain rights in this invention. Technical field

[0003] The present invention relates to a method for catalytically converting alkanes to their corresponding olefins, and a catalyst suitable for the method. Background technique

[0004] The well-known industrial method for producing monomers such as unsaturated carboxylic acids and unsaturated nitriles usually uses one or more olefins as raw materials and converts them into the desired monomer products through catalytic gas phase oxidation. Due to the pressure of industrial competition and the price difference between alkanes and corresponding alkenes (such as propane and propylene), people are working hard to develop some methods that use alkanes as raw materials to finally produce the required monomers at a lo...
