    • The present invention relates to a preparation method for zeolite molecular sieves. The object of the present invention is to provide a method for synthesizing zeolite molecular sieves by means of solid-state reactions without the usage of organic templates. The method comprises 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 ℃. After filtering and drying the crystallized products, molecular sieves in a powder form can be obtained. By using the method of the present invention, 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 can be obtained. The obtained products exhibit a high crystallinity and a high purity, and the method of the present invention does not require the use of organic templates and solvents, which avoids unnecessary consumptions during the production, simplifies the synthetic process, and also increases the yield from the autoclave reactor.
