Description
技术领域
本发明涉及一种双功能多级孔分子筛催化剂及其制备方法，属于生物质及废弃物能源化利用领域。
背景技术
能源危机及环境污染问题日益严重，因此，将低值生物质及废弃高分子材料转化为能源及化工原料意义重大，已经成为世界各国的能源战略之一。快速催化热解技术可以将生物质及废弃高分子材料转换为高品质的生物油、燃气和生物炭，具有广阔的市场前景和重要的社会价值。
该技术的关键点之一是选用性能优良的催化剂，一方面能有效提高反应转化率和目标产物的选择性，另一方面自身稳定性要好、不易失活。ZSM-5分子筛由于其特有的晶体结构和孔隙尺寸，对芳香类化合物和烯烃类化合物有很好的选择性，是当今化学工业上使用最广泛的分子筛催化剂，但其用于大分子体系反应过程中稳定性不好，易于失活。另外，生物质快速热解过程中反应随机性强，反应过程复杂，产物众多，目标反应的催化机理不尽相同，单一的催化剂活性点位只能促进单一类型的反应过程，导致产物选择性不高。
发明内容
针对以上问题，本发明的目的是提供一种双功能多级孔分子筛催化剂及其制备方法，该催化剂具有多级孔隙结构，含有路易斯酸点和布朗斯特酸点两种催化活性中心，具有两种催化功能，适合于生物质等大分子反应体系，有利于提高芳香类及烯类目标产物的选择性，制备方法简单，操作方便，易于工业化生产。
本发明提出了一种双功能多级孔分子筛催化剂及其制备方法，其特征在于该催化剂由ZSM-5分子筛颗粒在纳米尺度上并列排布，形成结构规整的晶体结构，颗粒之间的空隙形成尺寸不一的中孔，颗粒内部保持了ZSM-5的微孔结构，形成了多级孔结构，其微孔孔径为0.55~0.65 nm，其介孔尺寸为1nm~100 nm，分子筛结构上含有路易斯酸点和布朗斯特酸点，路易斯酸点强度和布朗斯特酸点的强度比可调；所述双功能多级孔分子筛催化剂的制备按照以下步骤进行：
（1）按照各组分比例配制溶液，具体过程为：将一定量的浓度为10 M的NaOH溶液和去离子水加入浓度为1 M的TPAOH溶液中充分混合，之后将一定量的Ludox HS-40逐滴加入上述混合溶液中，并搅拌1h形成透明溶液，最后将一定量的Aluminum isopropoxide加入上述混合溶液中，并搅拌30min，最后配制的溶液中各成分的比例为：SiO2 : 0.25 TPAOH :(0.006~0.02) Al2O3 : 0.014 Na2O : 16.44 H2O；
（2）利用水热法进行结晶，具体过程为：将上述配制的混合溶液置入特氟龙内衬的金属反应器中，在90~135 oC的条件下处理48~72 h，将得到的固体物质使用蒸馏水清洗后在100oC 的温度下过夜干燥，干燥后置于管式炉内煅烧12 h，煅烧温度为550 oC；
（3）采用原子植入的方法引入路易斯酸点，具体方法是将上述得到的固体物质先进行脱铝，再在加入金属离子溶液，在水热环境下处理12~120 h，这些金属离子包括Al, Ga,Sn, Ti, Zr或它们的组合。
所述的ZSM-5分子筛催化剂颗粒是球形，颗粒粒径范围为10~100nm。
所述的路易斯酸点强度和布朗斯特酸点的强度为0.1~100。
所述的ZSM-5分子筛的Si/Al为15~300。
该催化剂应用于农林废弃物、废旧塑料、食品废物、碳水化合物或其组合物等大分子反应体系，并将其转化生成芳香类及烯烃类产物。
所述的农林废弃物包括各种木材、藤条、竹材、纤维素、半纤维素、木质素、玉米秸秆、其它农林废弃物或它们的组合。
所述的芳香类产物包括苯、甲基苯、乙基苯、萘、甲基萘、茚、甲基茚及它们的同分异构体。
所述的烯烃类产物包括乙烯、丙烯、丁烯及它们的同分异构体。
