microporous crystalline zeolite material (ITQ-20) and its method of obtention.

摘要

microporous crystalline zeolite material (ITQ-20) and its preparation process.; A microporous crystalline material of zeolitic nature (ITQ 20) and preparation process.; A microporous crystalline material of zeolitic nature, having the empirical formula x (M1 / n XO 2): y YO2: (1-y) SiO2, wherein x has a value less than 0.2; and it has a value less than 0.1; M is at least one inorganic cation of charge + n; X is at least one chemical element with oxidation state +3, preferably selected from Al, Ga, B, Cr, Fe; and Y is at least one chemical element with oxidation state +4, preferably Ge, Ti, Sn, V.; This material is obtainable by a process comprising: preparing a laminar precursor, crystallized from a reaction mixture; subjecting the precursor to swell in a solution to obtain a swollen laminar washing and dried to obtain a swollen solid material; subjecting the solid to obtain a delaminated delaminated material for suspension; separating the delaminated material and remove organic residues by cation exchange and / or calcining.
