具有晶面取向的小颗粒MOR沸石的制备方法
摘要：
本发明属于无机材料技术领域，具体为一种具有晶面取向的小颗粒MOR沸石的制备方法。本发明的MOR沸石不仅有特殊的晶面取向，而且颗粒大小为纳米级别。该方法是采用水热合成法，将硅源，铝源，碱源，Beta晶种，无机盐和水相混合，并搅拌成凝胶状混合物作为合成MOR沸石的原料。此种特殊结构MOR沸石的化学组成为：TO2：aY2O3:bM2/nO，其中T代表了至少一种四价元素,如Si、Ge等，Y代表了至少一种三价元素，如Al、B、Ga、Fe等，M代表了至少一种碱金属或碱土金属元素，价态为n，a，b分别为Y2O3及M2/nO的摩尔数；a的范围为0～0.5，b的范围为0～0.5。本发明方法成本较低，无环境污染，适于推广应用。
摘要（英）：

The invention belongs to the technical field of inorganic materials, particularly a preparation method of granular MOR zeolite with crystal face orientation. The MOR zeolite has the special crystal face orientation, and the granular size is nano size. By adopting a hydrothermal synthesis method, a silicon source, an aluminum source, an alkali source, a Beta crystal seed, an inorganic salt and a water phase are mixed and stirred into a gel mixture which is used as a raw material for synthesizing the MOR zeolite. The chemical composition of the MOR zeolite in such special structure is TO2:aY2O3:bM2/nO, wherein T represents at least one quadrivalent element, such as Si, Ge and the like; Y represents at least one trivalent element, such as Al, B, Ga, Fe and the like; M represents at least one alkali metal or alkali earth metal element, and the valence state is n; a and b are respectively mole numbers of Y2O3 and M2/nO; and a is 0-0.5, and b is 0-0.5. The method has the advantages of lower cost and no environmental pollution, and is suitable for popularization.
