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 mum, 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 mum 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.
