Effect of catalytic combustion of hydrogen on the dehydration processes in a membrane reactor. III. calculation of the industrial reactor

Аннотация

This paper describes the mathematical simulation of an industrial membrane reactor for propane dehydrogenation in the thermodynamic coupling 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 input could be reduced to 500◦C. 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 devices at higher temperatures.
