SYNTHESIS METHOD OF NAA ZEOLITE MOLECULAR SIEVE MEMBRANE ON MACROPORE CARRIER

Title:

SYNTHESIS METHOD OF NAA ZEOLITE MOLECULAR SIEVE MEMBRANE ON MACROPORE CARRIER

Document Type and Number:

WIPO Patent Application WO/2012/010069

Kind Code:

A1

Abstract:

A synthesis method of NaA zeolite molecular sieve membrane on macropore carrier comprises coating a continuous and uniform crystal seed layer on the surface of the macropore carrier by using thermo-dipping and brush-coating method. The growth and separation performance of the synthesized membrane can be regulated with different grain sizes of the crystal seeds. A synthesis liquid is prepared according to the molar ratio of Na2O:SiO2:Al2O3:H2O=1-20:2-5:1:100-1000. Dynamically hydrothermal crystallization is performed in a rotary oven to synthesize the NaA zeolite molecular sieve membrane with excellent separation performance. The synthesized NaA molecular sieve membrane has excellent separation performance, high reusability and suitability for large-scale application.
