摘　　要：综述了SSZ-13沸石膜的制备及其用于分离CO_(2)的研究进展。讨论了合成方法、合成条件和表面改性对SSZ-13沸石膜的影响。探讨了SSZ-13沸石膜的分离稳定性及在不同条件下的分离性能。SSZ-13沸石膜作为一种无机膜,具有疏水性、高比表面积、独特的孔径、良好的物化稳定性等优点,在分离CO_(2)方面具有广阔的应用前景。指出了非沸石孔隙是目前制约SSZ-13膜分离性能的重要因素,厚度薄、无缺陷、分离性能稳定是SSZ-13膜的发展方向,为今后开发高性能的SSZ-13膜提供参考。This paper summarizes the preparation of SSZ-13 zeolite membranes and the application of SSZ-13 membranes in CO_(2) separation.The effects of synthesis methods,synthesis conditions and surface modification on SSZ-13 zeolite membranes are discussed.The separation stability and separation performance under different conditions of SSZ-13 zeolite membranes are reviewed.As inorganic membranes,SSZ-13 zeolite membranes has the advantages of hydrophobicity,high specific surface area,distinctive pore size and good physicochemical stability,which has good prospects in CO_(2) separation.However,the non-zeolitic defect is an important factor restricting the separation performance of SSZ-13 membranes.It is pointed out that thin thickness,defect-free and stable separation performance are the development direction of SSZ-13 membranes,which can provide reference for the preparation of high-performance SSZ-13 membranes.
