Separation technology, as a basic operating unit in the chemical production process, provides a large number of purification products for modern industry. The preparation and use of molecular sieve membranes has been gradually developed, has been a hot spot in the development of thin film technology today. MFI is currently the most widely studied and matured molecular sieve, with a unique pore structure, and different orientation of MFI zeolite molecular sieve membrane shave has different separation effects. MFI molecular sieve membranes have been gradually applied in the separation of various fields in industry. This paper summarizes the application of MFI molecular sieve membranes for membrane separation in recent years, mainly from different separation mate-rials to analyze their separation performance. Finally, the prospect of the development of MFI type zeolite molecular sieve membrane is made.
