    • PROBLEM TO BE SOLVED: To provide a heat crack-prevented zeolite separation film, and a method of manufacturing the same.SOLUTION: The method includes steps of: preparing an aqueous solution by dissolving an alumina-based raw material, a silica-based raw material and sodium hydroxide to water; preparing a hydrothermal solution by agitating the aqueous solution; preparing a seed crystal slurry through wet vibratory grinding and centrifugal separation of zeolite powder; passing seed crystals to the support by vacuum filtration to adhere the seed crystals to a surface of the support and further adhere them to permeate from a region 3 μm in depth from the surface of the support to a region of 50% of the overall thickness of the support; and putting the hydrothermal solution to a hydrothermal reactor, submerging the support with the seed crystals adhered thereto to the hydrothermal solution to perform hydrothermal treatment thereon, to thereby develop a compact zeolite separation layer not only on the surface of the support but also to the inside of the support. According to these steps, heat crack of the zeolite separation layer can be reduced, and the zeolite separation film can exert stable and excellent separation performance in a heating process and at an intended process temperature.
    • 要解决的问题:提供耐热裂纹防止沸石分离膜及其制造方法。 解决方案:该方法包括以下步骤:通过将氧化铝基原料,二氧化硅基原料和氢氧化钠溶解在水中来制备水溶液; 通过搅拌水溶液制备水热溶液; 通过湿式振动研磨和离心分离沸石粉制备晶种浆料; 将晶种通过真空过滤将晶种粘附到载体上以将晶种粘附到载体的表面上,并进一步将它们从载体表面的深度为3μm的区域渗透到总体厚度的50%的区域 支撑; 并将水热溶液放入水热反应器中,将其上粘附有晶种的晶种浸入水热溶液中进行水热处理,从而不仅在支撑体的表面上而且内部形成紧密的沸石分离层 的支持。 根据这些步骤,可以降低沸石分离层的热裂纹,并且沸石分离膜可以在加热过程和期望的工艺温度下发挥稳定和优异的分离性能。 版权所有(C)2012,JPO&INPIT
