Abstract
The invention concerns NU-88 zeolite, characterized by: PA0 i) a chemical composition with the following formula, expressed in terms of the mole ratios of the oxides for the anhydrous state: EQU 100 XO.sub.2, mY.sub.2 O.sub.3, pR.sub.2/n O where PA1 m is 10 or less; PA1 p is 20 or less; PA1 R represents one or more cations with valency n; PA1 X represents silicon and/or germanium; PA1 Y represents one or more of the following elements: aluminium, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese; and PA0 ii) an X ray diffraction diagram, in its as synthesized state, which comprises the results shown in Table 1 of the description. The invention also concerns the preparation of the zeolite, any catalyst containing the zeolite and any catalytic process using such a catalyst.
