Description
技术领域
本发明涉及一种制备MTO催化剂载体的方法，属于化工合成技术领域。
背景技术
MTO(Methanol To Olefin)是指由甲醇制取低碳烯烃（乙烯和丙烯）的化工工艺技术，为烯烃生产寻找了一条新的原料路线。不用石油而以甲醇为原料生产烯烃，不仅可使烯烃价格摆脱石油产品的影响，还能减少我国对石油资源的过度依赖。
MTO技术的关键是高性能催化剂的研制，早期对于MTO催化剂的研究主要以ZSM-5等中孔分子筛为主，ZSM-5的中大孔结构使其具有低碳少、寿命长等优点，但是由于其酸性太强，同时又具有烯烃收率低副产物多等缺点。1984年，UCC公司发明了SAPO-34分子筛用于MTO反应，其较小的孔径和较大的比表面积加快了MTO反应速率并且提高了反应的选择性，但是具有积碳高、易失活和寿命短等缺点。
鉴于甲醇制烯烃反应中的应用，需要制备一种ZSM-5/磷酸铝复合分子筛，与ZSM-5相比，ZSM-5/磷酸铝复合分子筛表现出了良好的协同作用和优良的催化性能。
发明内容
为了解决上述技术问题，本发明的目的是提供一种制备MTO催化剂载体的方法，具体步骤如下：
（1）取粒径均为40-50nm的二氧化硅、二氧化钛和氧化银的混合粉体加入容器中，其中二氧化硅、二氧化钛和氧化银的质量比为2.8：2：1.6，而后加入聚乙烯醇和水的混合溶液，室温下搅拌分散60分钟，而后加入硅烷偶联剂KH550和酸，其中KH550与酸的摩尔比为1:1，70℃搅拌反应5h，而后降温至室温，过滤，得到纳米改性复合粉体；
（2）将铝源、磷源加入水中搅拌待溶解完全，再加入ZSM-5原粉和步骤（1）得到的纳米改性复合粉体继续搅拌，并加入模板剂、氢氟酸，待搅拌3～5小时后制得纳米改性分子筛合成凝胶；
（3）将步骤（2）的分子筛合成凝胶在150～190℃下晶化12～24小时后冷却至室温，过滤，洗涤、在60-80℃下干燥，再在350～580℃下焙烧4～8小时即得纳米改性复合分子筛；
（4）将步骤（3）中制得的纳米改性复合分子筛做为载体用于MTO催化剂。
所述铝源、磷源、模板剂、氢氟酸和水的摩尔比为铝源:磷源:模板剂: 氢氟酸：水=1:（1.0～1.5）:（0.5～2）:（0.1～0.2）：（50～300）；
所述的模板剂为吗啉、哌啶或吡啶。
所述的铝源为拟薄水铝石、异丙醇铝、氢氧化铝、氧化铝中的一种或两种任意比例的混合物。
所述的磷源为正磷酸。
步骤（1）中的酸选自盐酸、硝酸、甲酸、乙酸中的一种或几种。
步骤（3）中合成凝胶在160～180℃水热晶化18小时，干燥温度为60～80℃。
所述ZSM-5原粉的质量占分子筛合成凝胶总量的约1/10～1/5。
本发明的有益效果：
本发明制备纳米改性ZSM-5/AlPO4-34复合分子筛的方法简单，晶化时间较短，适于大规模生产应用，其经济效益显著。分子筛中还采用了特定配比的改性纳米复合粉体，经过表面改性的上述纳米复合粉体可有效改善分子筛的附着性、强度、韧性和耐高温性。ZSM-5/AlPO4-34复合分子筛特定组成中各组分的相互协同，在应用于MTO反应中能够显著提高反应的选择性和催化效率。
具体实施方式
实施例1
本实施例中纳米改性ZSM-5/AlPO4-34复合分子筛的制备方法具体包括以下步骤：
（1）取粒径均为40-50nm的二氧化硅、二氧化钛和氧化银的混合粉体加入容器中，其中二氧化硅、二氧化钛和氧化银的质量比为2.8：2：1.6，而后加入聚乙烯醇和水的混合溶液，室温下搅拌分散60分钟，而后加入硅烷偶联剂KH550和酸，其中KH550与酸的摩尔比为1:1，70℃搅拌反应5h，而后降温至室温，过滤，得到纳米改性复合粉体；
（2）按照摩尔比为（异丙醇铝+氧化铝）:正磷酸:（哌啶+吡啶）:氢氟酸：去离子水=1:1.0:0.5:0.1：50取各组分，将异丙醇铝和氧化铝石分别添加入到去离子水中搅拌6小时，待溶解完全后加入正磷酸搅拌3小时，再加入硅铝比为50的ZSM-5原粉和步骤（1）得到的纳米改性复合粉体继续搅拌，并加入哌啶和吡啶，以及氢氟酸，ZSM-5原粉的质量占分子筛合成凝胶总量的1/5，待搅拌3小时制得分子筛合成凝胶；
（3）将步骤（2）中分子筛合成凝胶移至带聚四氟乙烯内衬的不锈钢晶化釜中，在150℃下晶化24小时后冷却至室温，抽滤，洗涤至中性后在80℃下干燥6小时，再在580℃下焙烧4小时即得ZSM-5/AlPO4-34复合分子筛；
（4）将步骤（3）中制得的纳米改性复合分子筛做为载体用于MTO催化剂。
