混合模板法低成本合成SSZ-13分子筛的研究

以硅溶胶、硫酸铝、氢氧化钠和去离子水为原料，以N，N，N-三甲基金刚烷氢氧化铵和三乙胺为模板剂，采用传统的水热法快速合成了SSZ-13分子筛。采用X射线荧光光谱（XRF）、X射线衍射（XRD）和扫描电镜（SEM）表征产物。综合考察了碱度、水量、模板剂和晶种等因素对合成SSZ-13分子筛的影响，确定了最佳合成条件。在有晶种或无晶种条件下，通过引入辅助模板剂三乙胺，晶化2 d即可得到SSZ-13分子筛。该方法缩短了生产周期，降低了生产成本，具有广泛的工业应用前景。

Cheap and rapid synthesis of SSZ-13 zeolite with dual templates

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.
