Zeolita ITQ-3

Authors: Camblor, Miguel Ángel; Corma, Avelino; Villaescusa, Luis A.;
Abstract

La presente invención se refiere a un material cristalino microporoso de naturaleza zeolítica designado como ITQ-3, a su método de obtención y a sus aplicaciones. El material se caracteriza por su composición química y por su modelo de difracción de rayos X. En su forma anhidra y calcinada, la composición química de ITQ-3 se puede representar por la fórmula empírica: x(M_1/n XO2):yYO2:SiO2 en la que x tiene un valor inferior a 0,15, y puede ser igual a cero; e y tiene un valor inferior a 0,1, y puede ser igual a cero; M es H+ o un catión inorgánico de carga +n, X es un elemento químico con estado de oxidación +3 (Al,Ge,B,Cr) e Y es un elemento químico de estado de oxidación +4 (Ti, Ge, V); cuando x = 0 e y = 0, el material puede ser descrito como un nuevo polimorfo de sílice de naturaleza microporosa. En el modo de realización preferido de la presente invención ITQ-3 tiene, en estado calcinado y anhidro, la composición: x(HXO2):SiO2 donde X es un elemento trivalente y x tiene un valor inferior a 0,1 y puede ser igual a cero, en cuyo caso el material se puede describir por la fórmula SiO2.
