03/011 - Material cristalino poroso Zeolita ITQ-24, su procedimiento de preparación y su uso en la conversión catalítica de compuestos orgánicos

Se presenta un nuevo material cristalino microporoso con canales formados por anillos de 10 y 12 miembros que se cruzan. Este material tiene una superficie específica mayor de 400 m2.g-1 y puede prepararse con centros catalíticamente activos. // The invention relates to a porous crystalline material (zeolite ITQ-24), the preparation method thereof and the use of same in the catalytic conversion of organic compounds. More specifically, the invention relates to a synthetic porous crystalline material which is characterised in that it is formed by tetrahedrally-coordinated atoms which are interconnected by means of oxygens. Said material, which comprises a unit cell containing 56 tetrahedrally-coordinated atoms, is known as ITQ-24. Moreover, in the calcined anhydrous state, the material has chemical formula nM1/pXO2: YO2, wherein: X is at least one trivalent element, Y is at least one tetravalent element, n is between 0 and 0.2 and M is at least one charge compensation cation in oxidation state p.
