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·g_act.comp), with the degree of extraction of ultrapure hydrogen reaching ~15%.

利用高温合成技术开发烃脱氢膜

基于α-Al系的多孔催化活性膜₂ ö ₃已被合成。为了合成膜，将氧化镁和碳化硅的低共熔组成的粉末状添加剂通过在30至90MPa的压力下压缩并在1350℃下烧结而引入到初始的Al ₂ O ₃粉末中。为了使合成膜具有催化性能，将高达10％的Fe ₂ O ₃ -Cr ₂ O ₃添加到混合物中。丁烯为接通丁二烯的脱氢的α-Al ₂ ö ₃膜从反应区选择性除去氢的膜将1,3-丁二烯的生产速率从16.5 L /（hr·g _act.comp）提高到16.5 L /（hr·g _act.comp），超纯氢的提取率达到_〜15％ 。
