Abstract: The SSZ-13 zeolite was rapidly synthesized by traditional hydrothermal method with silica solution,aluminium sulfate,sodium hydroxide,and deionized water as raw materials,and with the N,N,N-trimethyl-1-adamantammonium hydro- xide and tri-ethylamine as the templates.The synthetic product was characterized by X-ray fluorescence analysis(XRF),X- ray diffraction spectrum(XRD),and scanning electron microscopy(SEM).The influences of alkalinity,water quantity,tem- plate,and seeds etc. on the synthesis of SSZ-13 zeolite were investigated and the optimal synthesis conditions were deter- mined.The results showed: when using the dual templates with or without seed,the crystallization time could be shorten less than 2 d,which shorten the production cycle and reduce the production costs significantly.Therefore,the synthesis method mentioned above has a broad prospect of industrial application.
