Description
技术领域
本发明涉及具有菱沸石晶体结构的沸石的新合成方法以及根据本发明的合成方法合成的沸石材料作为催化剂的用途。
背景
沸石或分子筛被描述为由TO4四面体(T=Si、Al、P、Ge、B、Ti、Sn等)通过氧原子互连而形成的材料,以在整个分子范围上产生尺寸和形状均匀的孔和空腔。这些沸石材料作为催化剂、吸附剂或离子交换剂等具有重要的应用。
沸石可以根据其通道和孔的尺寸进行分类。在这方面,具有受8-T原子限制的通道的沸石称为“小孔沸石”(大约的开口),具有受10-T原子限制的通道的沸石称为“中孔沸石”(大约的开口),具有受12-T原子限制的通道的沸石称为“大孔沸石”(大约的开口),以及最后,具有受大于12-T原子限制的通道的沸石称为“超大孔沸石”(大于的开口)。
在国际沸石协会(IZA)接受的200多种沸石结构中,菱沸石晶体结构是最有趣的一种,因为其在许多不同应用中具有应用,最值得注意的是作为甲醇至烯烃(MTO)方法和NOx的选择性催化还原(SCR)中的非均相催化剂。
IZA将代码CHA指定给分子筛菱沸石,其具有通过大空腔相互连接的小孔的三向系统所形成的晶体结构。CHA结构已经通过各种化学组成合成,最值得注意的是铝硅酸盐(“SSZ-13”;Zones,美国专利4544538,1985,归属于Chevron)或硅铝磷酸盐(“SAPO-34”;Lok等人,美国专利4440871,1984,归属于UOP)。
通常,可以说铝硅酸盐显示出比同质硅铝磷酸盐更高的水热稳定性和更好的酸性质(Katada等人,J.Phys.Chem.C.,2011,115,22505)。因此,以经济的方式合成具有良好的物理化学性质的铝硅酸盐形式的CHA结构对于在工业过程中的应用将是非常有意义的。
菱沸石是具有以下化学组成的天然沸石:Ca6Al12Si24O72。除了菱沸石的天然形式之外,这种沸石结构已经在实验室中使用不同的无机碱性阳离子作为无机结构导向剂(SDA)合成。因此,已经公开了以下合成:沸石K-G(J.Chem.Soc.,1956,2822),其是在钾阳离子存在下合成的并具有1.1-2.1的Si/Al比的菱沸石;沸石D(英国专利868846,1961),其是在钠-钾阳离子存在下合成的并且具有2.2-2.5的Si/Al比的菱沸石;以及沸石R(美国专利3030181,1962,归属于Union Carbide),其具有1.7-1.8的Si/Al比。
最有可能的是,Tsitsishrili等人公开了有机结构导向剂(OSDAs)在沸石菱沸石的合成中的首次使用(Soobsch.Akad.Nauk.Cruz,SSR,1980,97,621),他们示出了在反应混合物K2O-Na2O-SiO2-Al2O3-H2O中存在四甲基铵(TMA)阳离子。然而,在最终固体中获得的Si/Al比非常低(Si/Al~2.1)。该文章公开了在合成介质中TMA的存在似乎影响CHA的结晶,但是所述有机分子未被掺入合成材料中。
通常,具有低Si/Al比(低于5)的铝硅酸盐显示低的水热稳定性。因此,为了提高CHA合成中的Si/Al比,较大的OSDA,例如N,N,N-三烷基-1-金刚烷基铵、N-烷基-3-奎宁环醇和/或N,N-三烷基-外氨基降冰片烷(Zones,美国专利4544538,1985,归属于Chevron)被引入合成介质中。通过使用这些OSDA,获得Si/Al比在4-25之间的沸石CHA,称为SSZ-13。
用于合成沸石SSZ-13的优选的OSDA是N,N,N-三甲基-1-金刚烷铵(TMAdA)阳离子。但是,所述OSDA成本很高。这种高成本可能限制沸石SSZ-13在工业过程中的商业用途。因此,使用更经济的OSDA来合成沸石SSZ-13对于所述沸石的潜在商业应用将是非常有意义的。
在制备沸石SSZ-13中降低TMAdA阳离子含量的替代方案包括引入TMAdA与另一种更经济的OSDA例如苄基三甲基铵的混合物(Zones,美国专利2008/0075656,2008,归属于Chevron)。在该发明中,通过将苄基三甲基铵阳离子引入至合成介质中,显著降低了TMAdA含量。尽管当制备沸石SSZ-13时使用这些OSDA混合物降低了成本,但仍然需要存在成本高的TMAdA阳离子。
类似地,已经提出在合成介质中使用OSDA TMAdA和四甲基铵(TMA)的混合物来合成CHA的铝硅酸盐形式(Bull等人,WO2011/064186,2011,归属于BASF)。尽管当制备沸石SSZ-13时使用这些OSDA混合物降低了成本,但仍然需要存在成本高的TMAdA阳离子。
最近,已经公开了使用新的,比原始的OSDA TMAdA更经济的有机分子作为合成介质中的唯一OSDA来合成铝硅酸盐形式的CHA。所述有机分子是苄基三甲基铵(Miller等人,美国专利8007764,2011,归属于Chevron),环烷基铵(Cao等人,美国专利2008/0045767,2008,归属于ExxonMobil;Feyen等人,WO2013/182974,2013,归属于BASF),N,N-二甲基哌啶鎓(Yilmaz等人,WO2013/035054,2013,归属于BASF)和N-烷基-1,4-二氮杂双环[2.2.2]辛烷阳离子和其衍生物(Zones,WO2010/114996,2010,归属于Chevron)。
除了上述的OSDA之外,最近还公开了使用胆碱合成铝硅酸盐形式的CHA(Chen等人,Environ.Sci.Technol.,2014,48,13909)。在该出版物中,作者声称胆碱的使用允许以经济的途径合成CHA。然而,为了有效地合成材料及其在工业中的后续商业应用,不仅在其制备中使用的源必须具有经济上的吸引力,而且材料制备过程也必须表现出良好的产率。在这种情况下,材料的起始Si/Al比为20(如可从该出版物中描述的SSZ-13的实验合成过程中所计算的);然而,获得的结晶固体的最终Si/Al比为6.5。所述差异表明合成产率小于30%(所获得的结晶固体随着在凝胶制备期间引入的无机氧化物而变化)。这种低产率将阻止所述合成方法在潜在工业应用中的使用。
近年来,已经公开了其中掺入了Cu阳离子(Cu-CHA)并具有CHA晶体结构的沸石材料是选择性还原运输相关的排放物中的NOx的有效的非均相催化剂。由于CHA结构的小孔的存在以及CHA腔中的Cu阳离子的稳定性,这些催化剂显示出高的水热稳定性。这些催化剂能够在水的存在下耐受大于700℃的温度。
尽管近年来在使用更经济的OSDA合成沸石SSZ-13方面取得了一些进展,但是很明显,仍然需要化学工业去改善所述晶体结构的合成,以适用于各种催化应用,更特别是,以使其用作处理来自汽车的气体排放物中的NOx的催化剂和/或载体。
发明内容
本发明涉及具有菱沸石结构(CHA)的沸石的新合成方法(其使用市售和经济的OSDA),以及所合成的沸石作为催化剂随后在各种催化过程例如甲醇至烯烃和气体排放物中NOx的选择性催化还原(SCR)中的用途。

特别地,已证实,四乙基铵(TEA)阳离子允许以较低的经济成本合成具有菱沸石结构的沸石,因为所述有机分子是市售的,此外,其所需要的前体比所需用于制备用于合成具有菱沸石结构的沸石的上述许多更复杂的有机分子的前体更经济。此外,本方法允许以高产率(大于80%)获得所期望的结晶材料。
