Abstract: Compared with traditional separation technologies, membrane separation technology has the advantages of high separation efficiency, low energy consumption, and is easy to integrate with other technologies. Compared with organic separation membranes, inorganic membranes have the advantages of high stability, large mechanical strength, high separation efficiency, and resistance to microbial erosion. This paper introduces the types of commonly used molecular sieve membranes, discusses the main preparation methods of molecular sieve membranes, and elaborates on the application progress of molecular sieve membranes in the fields of pervaporation and gas separation, such as hydrogen recovery, natural gas purification, carbon dioxide capture, and hydrocarbon mixture separation. The existing problems are analyzed, and the future development is prospected, emphasizing the research focus on reducing manufacturing costs, improving the preparation technology of molecular sieve membranes, and meeting the challenges of multi-component separation.
