The invention relates to a microporous crystalline zeolite material which, in the calcined state and in the absence of defects in the crystalline lattice thereof, manifested by the presence of silanols, has empirical formula x(M1/nXO2):yYO2:SiO2, in which M is selected from among H+, at least one inorganic cation with charge +n and a mixture of both; X is at least one chemical element in oxidation state +3; Y is at least one chemical element in oxidation state +4, which is different from Si, x has a value of between 0 and 0.2 inclusive, and y has a value of between 0 and 0.1 inclusive. In addition, as it is synthesised, and in the calcined state, the material has a characteristic X-ray diffraction pattern known as ITQ-32. The invention also relates to the method of preparing said material and to the use thereof.
本发明涉及一种微孔晶体沸石材料,其在经过煅烧并且晶格中没有缺陷(由硅醇的存在表现出来)的情况下,具有经验式x(M1/nXO2):yYO2:SiO2,其中M选自H+,至少一种带电+n的无机阳离子和两者的混合物;X至少是一种氧化态为+3的化学元素;Y至少是一种氧化态为+4的化学元素,不同于Si;x的值在0至0.2之间,包括0和0.2;y的值在0至0.1之间,包括0和0.1。此外,该材料在合成和煅烧状态下具有一种特征的X射线衍射图案,称为ITQ-32。本发明还涉及制备该材料的方法及其用途。
