| abstract |
The invention relates to a microporous crystalline zeolite material (ITQ-22) having, in the calcined state, empirical formula x (M1/nXO2): y YO2: z GeO2: (1-z) SiO2, wherein M is H+ or at least one inorganic cation of charge +n; X is at least one chemical element in oxidation state +3, preferably Al, Ga, B, Fe and Cr; Y is at least one chemical element in oxidation state +4, which is different from Si and Ge, preferably Ti, Sn and V; x has a value less than 0.2, preferably less than 0.1, and can be equal to zero; y has a value less than 0.1, preferably less than 0.05, and can be equal to zero; and z has a value less than 0.8, preferably between 0.005 and 0.5, and can be equal to zero. The inventive material has a typical X-ray diffractogram. The invention also relates to the method of preparing said material and the use thereof in processes involving the separation and transformation of organic compounds. |
