摘要
Beta沸石分子筛是一种具有三维十二元环孔结构的高硅沸石分子筛,具有独特的催化性能,在石油炼制及精细化工中有着广泛的应用。本文以四乙基溴化铵(TEABr)和四乙基氢氧化铵(TEAOH)为模板剂,以硅溶胶或硅胶粉末为硅源,以铝酸钠为铝源通过水热晶化法合成了Beta分子筛,并通过XRD等手段对合成样品进行表征。同时详细考察了模板剂浓度、晶化温度、晶化时间等因素对Beta分子筛晶化过程的影响,得到了合成Beta分子筛的最佳合成条件。
Beta zeolite is synthesized with tetraethylammonium hydroxide or tetraethylammonium bromide as the template agentand silica sol or silica gel powder as silicon source and characterized by XRD. To obtain detailed information on the rules ofsynthesized chemistry, the effeets of TEABr/SiO2 , crystallization time, crystallization temperature on Beta zeolite erystallinitywere systematically studied. The results suggest that the use of TEABr as an organic template and silica sol as silicon iscommercially economical.
