Title:
METHOD FOR SYNTHESIZING HIGH WATER PERMEABILITY MOLECULAR SIEVE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/166509
Kind Code:
A1
Abstract:
A method for synthesizing a high water permeability molecular sieve membrane, comprising the following steps: dispersing a zeolite molecular sieve seed crystal in deionized water to obtain a seed crystal solution; introducing a seed crystal layer on the surface of a porous carrier by using the seed crystal solution, dissolving NaOH, an Al source, an Si source, and NaF in the deionized water, formulating to prepare a synthesis solution, immersing the porous carrier loaded by the seed crystal in the obtained synthesis solution for 1-200 s, and then directly crystallizing.
