a catalyst, a comprehensive euo - zeolite, a 10 - mr zeolite and a 12 - mr zeolite and its use in the isomerisation of aromatic c8 compounds

摘要

Catalyst comprises an EUO zeolite (I), a zeolite (II) with channels with openings defined by a ring having 10 oxygen atoms, a zeolite with at least channels with openings defined by a ring having 12 oxygen atoms and a porous mineral matrix. An independent claim is included for a process of isomerization of an eight carbon aromatic feed comprising reaction of the feed in the presence of the catalyst.
