Microporous amorphous material, preparation method thereof and use of same in the catalytic conversion of organic compounds

Abstract

[EN] The invention relates to a microporous amorphous material which is characterised in that it has a chemical composition in the calcined and anhydrous state which can be represented by empirical formula x (M1/nXO2): y YO2: SiO2, wherein: x has a value of less than 0.2 and can be equal to zero; y has a value of less than 0.2 and can be equal to zero; M is selected from among H, one or more inorganic cations having a +n charge and a mixture of same; X is one or more chemical elements in oxidation state +3; and Y is one or more elements in oxidation state +4. The inventive material is also characterised in that it has a uniform pore distribution, a micropore volume of greater than or equal to 0.05 cm.g and a specific surface area of greater than 100 m.g. The invention also relates to the preparation method thereof and use of same.

[ES] La presente invención se refiere a un material amorfo microporoso caracterizado porque tiene una composición química en el estado calcinado y anhidro que puede representarse por la fórmula empírica: x (Ml/nX02) : y YO2 : SiO2 en la que: x posee un valor inferior a 0.2; pudiendo ser igual a cero, y tiene un valor menor de 0.2; pudiendo ser igual a cero, M está seleccionado entre H, uno o varios cationes inorgánicos de carga +n; y una mezcla de los mismos, X es uno o varios elementos químicos de estado de oxidación +3, e Y es una o más elementos en estado de oxidación +4, que, tiene una distribución uniforme de poro y un volumen de microporo mayor o igual de 0.05 cm.g y que tiene una superficie especifica superior a 100 m.g; a su procedimiento de preparación y a su uso.
