  • SiO 2 mesoporous material namely SBA-15 molecular sieve
  • ethyl orthosilicate, methyl orthosilicate, and butyl orthosilicate are used as silicon sources to synthesize a new ordered SiO 2 mesoporous material, namely SBA-15 molecular sieve, in an acidic environment.

There are a lot of silanol on the surface.
  • SBA-15 molecular sieve is a pure silicon ordered mesoporous zeolite material with almost no acidity and poor stability, which limits its industrial application in the petrochemical industry.
  • the method of introducing heteroatoms is usually used to modify SBA-15 molecular sieve, and the introduction of aluminum atoms into SBA-15 molecular sieve to synthesize Al-SBA-15 molecular sieve is one of the most commonly used modification methods.

  • CN108946754A discloses a method for preparing aluminum-containing SBA-15 by using fly ash acid extraction aluminum residue as a raw material. The above two methods first extract the silicon source and aluminum source from kaolin or fly ash, and then use them as the raw material for the synthesis of SBA-15 molecular sieve.

Description

一种DLM-1分子筛及其制造方法和应用 技术领域
本发明涉及一种介孔分子筛，特别是一种DLM-1分子筛，属于Al-SBA-15分子筛。本发明还涉及所述分子筛的制造方法及其在有机物处理中的应用。
背景技术
根据国际纯粹和应用化学联合会(IUPAC)定义，孔径位于2至50nm的材料为介孔材料。1992年Mobil公司的科研人员首次使用烷基季铵盐为模板剂合成出M41S系列氧化硅基介孔材料。20世纪末，赵东元等(Zhao DongYuan，et al.Triblock copolymer syntheses of mesoporous silica with periodic 50 to 300 angstrompores[J].Science，1998，279(5350)：548-552.)首次提出采用三嵌段共聚物(P123)为模板剂，以正硅酸乙酯、正硅酸甲酯、正硅酸丁酯为硅源，在酸性环境中合成新型有序SiO 2介孔材料即SBA-15分子筛。它是一种高度有序平面六方相结构，具有二维六方孔道，孔径在5至30nm之间，孔壁厚度在3至6nm之间，孔道间有微孔相连的介孔材料，在其内表面存在大量的硅羟基。
SBA-15分子筛是纯硅型有序介孔沸石材料，几乎没有酸性，稳定性较差，这限制了其在石油化工领域的工业应用。目前通常采用引入杂原子的方法对SBA-15分子筛进行改性，其中SBA-15分子筛中引入铝原子以合成Al-SBA-15分子筛是最常用的改性方法之一。
通常，合成Al-SBA-15分子筛的方法主要有两种，即直接合成补铝和后处理嫁接法。在直接合成法中，在强酸性合成介质中，Al原子主要以阳离子形式存在，很难与SBA-15孔壁中的硅羟基物种直接聚合而以显著量进入其骨架中，Al原子不能很好分散在SBA-15中，多数以团聚形式存在，致使通过直接法合成的SBA-15中Al原子的引入效率很低。与直接合成法相比，后处理嫁接的方法虽可引入更多量的Al原子，但该合成方法过程较繁琐，且容易在材料孔道内部或外表面产生一些氧化铝的副产物，从而造成材料孔道堵塞，比表面积和孔体积显著降低，成为催化反应的不利因素。
CN104016369A公开了一种以高岭土为原料制备Al-SBA-15分子筛的方法。CN108946754A公开了一种以粉煤灰酸法提铝残渣作为原料制备含铝的SBA-15的方法。上述两种方法先是将高岭土或粉煤灰中的硅源和铝源提取出来，然后再作为SBA-15分子筛的合成原料，这样一方面容易引入其他杂质，另一方面仍存在常规直接合成补铝法的缺点。
发明内容
本发明的发明人发现，在现有技术所制造的Al-SBA-15分子筛中，铝很难以显著量进入分子筛的骨架结构，或者为了使铝以一定量进入分子筛骨架，则必须以更多量的铝附着在分子筛骨架外围(通常是分散在分子筛的孔道内表面)作为代价。具体而言，根据现有技术所制造的Al-SBA-15分子筛，在铝含量较低(比如氧化铝在分子筛化学组成中所占的质量百分比含量低于7重量％)的情况下，这类铝尚且能够实现在分子筛孔道内的高度分散而使得分子筛在整体上表现出规整的介孔结构，但是随着铝含量的增加(比如高于7重量％，特别是高于15重量％时)，这类铝开始在分子筛的孔道上局部或全面堆积，导致分子筛的孔道迅速缩小(一般表现为孔直径<4nm的小孔所占的比例迅速增加)甚至堵塞，分子筛的介孔结构的规整性相应降低甚至完全消失。为此，本发明的发明人通过刻苦的研究，发现了DLM-1分子筛，并基于该发现而完成了本发明。
本发明的发明人通过研究发现，所述DLM-1分子筛表现出Al-SBA-15分子筛的XRD谱图，属于Al-SBA-15分子筛。在不受任何理论限制的情况下，本发明的发明人认为，在本发明的DLM-1分子筛中，铝基本上进入了分子筛的骨架结构，由此即使是在铝含量非常高(比如氧化铝在分子筛化学组成中所占的质量百分比含量高于7重量％、甚至比如达到85重量％)的情况下，分子筛仍然显示出介孔结构的规整性。该规整性一般可以用分子筛的孔分布(特别是孔直径<4nm的孔的孔容比例)进行表征。作为佐证，根据本发明的DLM-1分子筛，即使氧化铝在分子筛化学组成中所占的质量百分比含量在2％至85％之间广泛变化，孔直径<4nm的孔所占的孔容仍然为总孔容的20％以下，保持了介孔结构的完整性和规整性，这是现有技术所制造的Al-SBA-15分子筛所不具备的。因此，本发明的DLM-1分子筛是一种新型结构的Al-SBA-15分子 筛。
