Abstract A synthesis method of small crystal grain beta-zeolite includes the following steps: dissolving aluminium source, tetraethyl ammonium cation source and alkali source in water to prepare a working solution, using silica-gel granules with 20-300 meshes granularity as silicone source, mixing the said silicone source and the above-mentioned working solution to obtain a reactive mixture, then adopting the hydrothermal crystallization process according to conventional condition and recovering the invented product. It is characterized by that in the described reactive mixture an organic additive is contained, and said organic additive is polyol type non-ionic surfactant or polyether-like lubricating oil or their mixture, the dosage of the said additive is 0.05-8% of weight of SiO2 being in reactive mixture.
