A porous catalytically active membrane based on α-Al2O3 has been synthesized. For the synthesis of the membrane, powdered additives of the eutectic composition of magnesium oxide and silicon carbide were introduced into the initial Al2O3 powder using compression at pressures of 30 to 90 MPa and sintering at 1350°C. To impart catalytic properties to the synthesized membrane, up to 10% Fe2O3–Cr2O3 was added to the mixture. Dehydrogenation of butylene to butadiene on an α-Al2O3-based membrane with selective removal of hydrogen from the reaction zone increased the rate of production of 1,3-butadiene from 16.5 to 20.6 L/(hr·gact.comp), with the degree of extraction of ultrapure hydrogen reaching ~15%.
