[EN] he invention relates to a material which, once calcined and in the anhydrous state, has general formula x (M1/nXO2): z ZO2: y GeO2: (1-y) SiO2, wherein x has a value of less than 0.2, preferably less than 0.15, and can equal zero; z has a value of between 0 and 0.1, preferably between 0 and 0.05; y has a value of between 0 and 1, preferably between 0 and 0.75; M represents one or more +n-charged inorganic cations; X represents one or more +3 oxidation state chemical elements (Al, B, Ga, Fe); and Z represents one or more +4 oxidation state cations different from silicon and germanium, preferably Ti or Sn. Said material can be used as a component of catalysts in acid catalysis processes or as a metal or oxide support in separation and absorption/adsorption processes.
[ES] Se describe un material que una vez calcinado y en estado anhidro responde, a la fórmula general X(Ml/nX02) : Q ZOz: y GeOz: (l-y)SiOz donde x posee un valor inferior a 0,2, preferentemente inferior a 0,15 y puede tomar el valor cero; z tiene un valor comprendido entre O y 1, preferentemente entre O y 0.75, ; M es uno o varios cationes inorgánicos de carga +n; X es uno o varios elementos químicos de estado de oxidación +3 (Al, B, Ga, Fe) y Z es uno o varios cationes en estado de oxidación +4 distintos de Silicio y Germanio, preferentemente, Ti o Sn. Este material es útil como componente de catalizadores en procesos de catálisis ácida, o como soporte de metales u óxidos, en procesos de separación y absorción/adsorción.
