Description
Summary:A porous catalytically active membrane based on α-Al 2 O 3 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 Al 2 O 3 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% Fe 2 O 3 –Cr 2 O 3 was added to the mixture. Dehydrogenation of butylene to butadiene on an α-Al 2 O 3 -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·g act.comp ), with the degree of extraction of ultrapure hydrogen reaching ~15%.
