Abstract: This paper describes the mathematical simulation of an industrial membrane reactor for propane dehydrogenation in the thermodynamic conjugation with hydrogen combustion (oxidation). Due to the effective removal of hydrogen through a membrane and the heat release as a result of an exothermic reaction, the temperature of the reaction stream at the inlet could be reduced to 500 gr. The fact that the process is carried out on an industrial-level membrane reactor makes it possible to reach a propane conversion of 75% with a propylene selectivity of 97%, which exceeds the figures obtained per pass in existing industrial device at higher temperatures.

Keywords: hydrogen combustion, propane dehydrogenation, thermodynamically conjugated processes, industrial membrane reactor, mathematical simulation.
