A MICROPOROUS CRYSTALLINE ZEOLITE MATERIAL (ITQ-20) AND A PRODUCTION METHOD THEREOF |
摘要 |
The invention relates to a mircroporous crystalline zeolite material having the empirical formula x(M1/nXO2): yYO2: (1-y)SiO2, wherein x has a value less than 0.2; y has a value less than 0.1; M is at least an inorganic cation with a +n charge; X is at least a chemical element having oxidation state +3, preferably selected from among Al, Ga, B, Cr, Fe; and Y is at least a chemical element with oxidation state +4, preferably Ge, Ti, Sn, V. The inventive material can be obtained by means of a process consisting in: preparing a laminar precursor, crystallised from a reaction mix; swelling the precursor in a solution in order to obtain a swollen laminar material which is then washed and dried to obtain a swollen solid; delaminating the solid to obtain a delaminated material in suspension; separating the delaminated material and eliminating the organic remnants by cationic exchange and/or calcination.
