EUO zeolite comprising crystals and aggregates of crystals with specific granulometrys and its use as a catalyst in the isomerisation of C8 aromatic compounds

摘要

The invention concerns a zeolite with structure type EUO comprising EUO zeolite crystals with a size of less than 5 m, at least a portion of the EUO zeolite crystals being in the form of EUO zeolite aggregates, characterized in that the granulometry of the aggregates is such that Dv,90 is 500 m or less. The invention also concerns the preparation of the zeolite and the use of the zeolite as a catalyst, for example in a process for isomerising aromatic compounds containing 8 carbon atoms per molecule.
