Development of a Membrane for Hydrocarbon Dehydrogenation Using High-Temperature Synthesis
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 an...
