Using the method of self-propagating high-temperature synthesis (SHS), porous metal-ceramic membranes based on a mixture of powders of aluminum oxide, silicon carbide, and magnesium oxide have been obtained. The membranes obtained are catalytically active, the surfaces of open pores in them are modified with rhenium-tungsten active components using the alkoxo method. At a temperature of 600 & # 176; C, the highest selectivity to propylene (& # 8776; 60 & # 37;) is achieved. In this case, the optimal conditions for the implementation of the propane dehydrogenation process is a temperature of 650 ° C, at which a fairly high selectivity for the most important monomers is maintained with a relatively small proportion of side processes
