A porous, catalytically active membrane based on coarse-fraction silicon carbide was synthesized. Ultrafine additives with an eutectic composition of magnesium oxide and silicon carbide, which during sintering at temperatures from 1100 to 1450°C form a liquid phase in the form of clinoenstatite MgSiO₃ that wets the coarse-size SiC particles and forms a strong porous framework of the membrane, were introduced into the initial SiC powder to synthesize the membranes. The pore size of the ceramic material was studied as a function of the pressing pressure, which made it possible to obtain a highly porous ceramic membrane with pore size optimized for dehydrogenation of ethylbenzene into styrene. Modification of the pore surfaces to 10% Re – W by means of active components using the alkoxy method is performed in order to give the synthesized membrane the catalytic properties required for realizing the dehydrogenation process.

合成了一种基于粗级碳化硅的多孔催化活性膜。具有氧化镁和碳化硅的低共熔组成的超细添加剂，在1100至1450°C的温度下烧结时，形成斜长辉石MgSiO ₃形式的液相将润湿粗大的SiC颗粒并形成坚固的多孔膜框架的方法引入到最初的SiC粉末中以合成膜。研究了陶瓷材料的孔径与压制压力的关系，从而有可能获得一种高度多孔的陶瓷膜，其孔径经优化可用于乙苯脱氢成苯乙烯。为了使合成膜具有实现脱氢过程所需的催化性能，使用烷氧基方法通过活性成分将孔表面改性为10％Re-W。
