Description
技术领域
本发明涉及分子筛领域，具体涉及一种B-EUO分子筛及其制备方法和应用。
技术背景
沸石分子筛是一类多孔的结晶材料，具有规整的分子尺寸孔道结构、较强的酸性和高的水热稳定性，被广泛应用于催化、吸附和离子交换等领域中，并起着不可替代的作用。
EUO分子筛是一种中孔高硅分子筛，具有一维网状微孔孔道结构，含有十元环直通孔道(孔口直径为0.54×0.41nm)及与之垂直联通的十二元环侧袋(开口尺寸为0.68×0.58nm，深度为0.81nm)结构。由于孔道的特殊性，EUO分子筛在二甲苯异构，直链烷烃异构化，加氢脱蜡等反应中表现出优异的催化性能，具有良好的工业应用前景。
EUO结构分子筛包括EU-l、TPZ-3和ZSM-50分子筛。欧洲专利EP 0042226A1最早提出EU-l分子筛及其制备方法，使用了聚亚甲基α-ω二铵烷基衍生物或所述衍生物的降解产物或所述衍生物前体作为模板剂制备得到。欧洲专利EP 0051318A1公开了一种TPZ-3分子筛，使用了与合成EU-l分子筛所使用的同组模板剂，特别介绍了1,6-N,N,N,N’,N’,N’-六甲基六亚甲基二铵(或称六甲双铵)化合物作为模板剂的制备方法。欧洲专利EP 0159845A2和美国专利US 4640829公开了一种ZSM-50分子筛，是使用二苯甲基二甲基铵衍生物作为模板剂合成的。美国专利US 20070117711中公开了使用N,N-二甲基-N,N-二(3,3-二甲基丁基)铵作模板剂合成EUO分子筛的方法。以上公开的EUO结构分子筛的合成方法均使用了昂贵的模板剂，为了降低成本，需改用更便宜的模板剂来合成分子筛。
某些反应，比如直链烷烃异构化要求催化剂的酸性不能太强，而硅硼分子筛比硅铝分子筛酸性更弱，在这类反应中可能具有更好的性能。现有技术中关于B-EUO分子筛的制备方法很少，EP 0051318A1中公开的TPZ-3和EP 0159845A2中公开的ZSM-50都是硅铝EUO分子筛；而EP 0042226A1中公开的EU-1分子筛的制备方法中，Si与三价骨架元素X的摩尔比例为SiO2/X2O3≥10，尽管专利中声明X可以是Al、B、Ga、Fe等多种元素，但实施例中未涉及到B-EUO分子筛的制备。由于B元素与Al元素性质的差异，在分子筛制备过程中，硅源与铝源缩合产物溶解性差、与水作用呈凝胶状，而硅源与硼源缩合产物溶解性好、在水中易形成澄清溶液，因此在实践中用于合成硅铝EUO分子筛的方法往往无法合成出B-EUO分子筛。另一方面，相比较低硅硼比EUO分子筛，高硅硼比EUO分子筛表现出更好的水热稳定性，在催化反应中具有更好的稳定性及更长的寿命。因此，制备高硅硼比的B-EUO分子筛意义重大。
