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.

Abstract: The present disclosure is directed to a method of manufacture of co-crystallized *BEA/MOR zeolites. This is accomplished by using an improved sol-gel formulation including a water-soluble fraction of ODSO as an additional component. The resulting products are, or contain, co-crystallized *BEA/MOR zeolites, whereas in the absence of the ODSO, the resulting products are zeolite beta.
