Abstract
In a method for preparing a zeolite CHA membrane, a gel conversion method is adopted to assist crystallization, seed solutions with different concentrations and sizes are successively coated on the surface of a porous support to obtain a seed layer, a synthetic gel is coated on the seed layer to obtain a gel layer, and then the porous support is subjected to a membrane crystallization reaction to obtain a zeolite CHA membrane. The method skips the conventional stage of converting the heterogeneous zeolite into the zeolite CHA seed, and directly takes a heterogeneous zeolite with the same secondary structural unit as that of zeolite CHA as a seed to directly prepare a zeolite CHA membrane on a support.
