PROCESS FOR THE CATALYTIC DEHYDROGENATION OF ALKANES TO ALKENES WITH SIMULTANEOUS COMBUSTION OF HYDROGEN

摘要

A process for the net catalytic oxidative dehydrogenation of alkanes to produce alkenes is provided. The process involves simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to drive the equilibrium dehydrogenation reaction further to the product alkenes. In the present reaction, the alkane feed is passed into a reactor containing both an equilibrium dehydrogenation catalyst and a reducible metal oxide, whereby the alkane is dehydrogenated and the hydrogen produced is simultaneously and selectively conbusted in oxidation/reduction (REDOX) reaction with the reducible metal oxide. This particular mode of operation is termed a same reactor, REDOX mode. The equilibrium dehydrogenation catalyst may comprise platinum and the reducible metal oxide may contain bismuth, antimony, indium, or molybdenum, or a mixture thereof.
