Abstract
The present disclosure relates to a preparation method of an SSZ-13 zeolite membrane, and belongs to the technical field of zeolite membranes. The present disclosure solves the problem that the SSZ-13 zeolite membranes synthesized in the art have a poor quality and a large thickness. In the present disclosure, a FAU-type zeolite is used as a raw material, and transformed into an SSZ-13 zeolite with a particle size of 210 nm through intergranular transformation, with a mass yield of 91.2%. A crystal seed prepared by the preparation method of the present disclosure has a small particle size and a small thickness.
