ABSTRACT:
A catalyst is described which comprises at least one zeolite with structure type EUO, at least one zeolite having channels the opening to which is defined by a ring of 10 oxygen atoms (10 MR), at least one zeolite having channels the opening to which is defined by a ring of 12 oxygen atoms (12 MR) and at least one porous mineral matrix. Said catalyst optionally also contains at least one group VIII metal. The catalyst of the invention is used in a process for isomerizing a feed comprising aromatic compounds containing 8 carbon atoms per molecule.
