Microporous crystalline zeolite material (zeolite ITQ-22), synthesis method thereof and use of same as a catalyst

Abstract

[ES] La presente invención refiere a un material cristalino microporoso de la naturaleza zeolítica (ITQ-22) que, en el estado calcinado, tiene la fórmula empírica en donde M es H+ o por lo menos un catión inorgánico del cargo +n X es por lo menos un elemento químico del estado de oxidación +3, seleccionado preferiblemente del aluminio, del Ga, del B, de la fe y del Cr que consisten en del grupo Y es por lo menos un elemento químico con el estado de oxidación +4 con excepción del silicio y de la GE, seleccionados preferiblemente del Ti, del Sn y del V que consisten en del grupo x tiene un valor más pequeño de 0.2, preferiblemente más pequeño de 0.1 y bote tenga el cero del valor, y tiene un valor más pequeño de 0.1, preferiblemente más pequeño de 0.05 y bote tenga el cero del valor, z tiene un valor más pequeño de 0.8, preferiblemente entre 0.005 y 0.5 y bote tienen el cero del valor, con un espectro de difracción de la radiografía de la característica, al método de preparación y al uso del material de tipo en la separación y procesos de transformación de compuestos orgánicos.

[EN] The present invention refers to a microporous crystalline material of zeolitic nature (ITQ-22) which, in the calcined state, has the empirical formula wherein M is H+ or at least one inorganic cation of charge +n; X is at least one chemical element of oxidation state +3, preferably selected from the group consisting of Al, Ga, B, Fe and Cr; Y is at least one chemical element with oxidation state +4 other than Si and Ge, preferably selected from the group consisting of Ti, Sn and V; x has a value less than 0.2, preferably less than 0.1 and can take the value zero, y has a value less than 0.1, preferably less than 0.05 and can take the value zero, z has a value less than 0.8, preferably between 0.005 and 0.5 and can take the value zero, with a characteristic X-ray diffraction pattern, to the method of preparation and to the use of the material in separation and transformation processes of organic compounds.
