摘要: 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。

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.

Key words: SSZ-13 zeolite;hydrothermal synthesis;N, N, N-trimethyl-1-adamantammonium hydroxide;tri-ethylamine
