<p>The invention relates to a microporous crystalline, zeolitic material, which, in a calcinated and anhydrous state, has a chemical composition that is represented by formula: x (M1/nXO2): y YO2: z GeO2: (1-z) TO2, wherein x has a value lower than 0.2, y has a value lower than 0.1, z has a value lower than 1, the value of at least one amongst x, z e y being higher than zero; M is H+ or at least one +n charged inorganic cation; X is at least one chemical element with a +3 oxidation state, Y is at least one chemical element with a + oxidation state and T is at least one chemical element with a +4 oxidation state (Si, Ti, Sn, V), said material having a particular x ray diffraction pattern. The invention also relates to a method for preparing said material and to its utilization as catalyst in processes for the separation and transformation of organic compounds.</p> |
