摘要：

具有CHA骨架结构的SAPO-34 分子筛及分子筛膜因其规整的孔道结构、适度且可调控的表面酸性、优良的热和水热稳定性在气体分离领域具有广泛的应用前景。本文主要介绍目前SAPO-34膜的合成方法，影响SAPO-34分子筛膜分离性能的主要因素，着重探讨了SAPO-34分子筛膜合成体系各参数的调控和优化策略，概述目前SAPO-34分子筛膜CO2/CH4分离领域研究现状和需要进一步解决的问题。分析CO2气体分离产工业化进程及存在的问题，并指出SAPO-34分子筛膜的研究发展方向。

SAPO-34 membrane with CHA framework structure have wide application prospects in gas separation and other fields due to their regular pore structure, moderate and adjustable surface acidity, excellent thermal and hydrothermal stability. In this review, we introduced the synthesis method, influencing factors and application of SAPO-34 membrane for CO2/CH4 separation, focused on the control and optimization strategy of parameters in the synthesis system of SAPO-34 membrane. Meanwhile, we summarized the current research status and problems to be further solved in the field of SAPO-34 membrane for CO2/CH4 separation, and pointed out the research and development direction of SAPO-34 membrane.
