The invention relates to a porous crystalline material (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/p XO2: 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.
L'invention concerne une matière cristalline poreuse (zéolite ITQ-24), son procédé de préparation et son utilisation dans la conversion catalytique de composés organiques. La présente invention se rapporte à une matière synthétique, poreuse et cristalline caractérisée en ce qu'elle est formée d'atomes en coordination tétraèdre unis entre eux à travers des oxygènes. L'invention présente une cellule unité contenant 56 atomes en coordination tétraèdre, que l'on appelle ITQ-24, dont la formule chimique à l'état calciné et anhydre est la suivante : dans laquelle X désigne au moins un élément trivalent, Y désigne au moins un élément tétravalent, la valeur de n étant comprise entre 0 et 0,2 et M représente au moins un cation de compensation de charge à l'état d'oxydation p.
