V.45.3.2.

Dehydrogenation of saturated hydrocarbons is known to be the key route to yield the monomers despite on having the strong endothermic and equilibrium limitations. The oxidative dehydrogenation (ODH) is free of latter restrictions but characterized with low product selectivity. The use of the catalytic membrane reactor (CMR) with additional hydrogen oxidation permits one to combine the advantages of conventional dehydrogenation and oxidative dehydrogenation processes. In this case the endothermic and exothermic processes are supposed to take place within the different compartments of the membrane reactor (so called thermodynamically “conjugated” reactions). The impact of membrane reactor parameters on performance of dehydrogenation processes has been theoretically investigated and compared with the tubular reactor. The dehydrogenation processes of ethane, propane and ethylbenzene were considered. The theoretical study was implemented by means of mathematical modeling. The use of the membrane reactor combined with hydrogen oxidation was found to be the most effective way to produce olefins via dehydrogenation process. Carrying out the dehydrogenation process in conjugated membrane reactor enables attainment of very high hydrocarbon conversions (98-100%) at considerably lower temperatures (500°С for ethane, 550°С for propane, and 600°С for ethylbenzene). Using the membrane reactor permits one to increase the conversion value by the selective hydrogen removal from the reaction zone and to shift the equilibrium towards the products.
