  • Patent number: 10160656
    Abstract: Described is a preparation method for zeolite molecular sieves by means of solid-state reactions without the usage of organic templates. The method comprises the following steps: grinding and mixing the solid raw materials comprising the silicon source, the aluminum source and the alkali source, transferring the obtained mixture into an autoclave, conducting the crystallization for a period of 5 hours-20 days at a temperature of 50-200° C. After filtering and drying the crystallized products, molecular sieves in a powder form can be obtained. The method provides different molecular sieves, including ZSM-5 zeolite, Beta zeolite, FAU zeolite, MOR zeolite, LTA zeolite, and GIS zeolite, with a high crystallinity and an adjustable Si/Al ratio within a certain range.
