An EUO-type zeolite is used as a selective catalyst for the isomerization of 8C aromatic compounds. The catalysts comprises a zeolite of structure EUO, partly in acid form, a matrix and a group VIII metal. The zeolite contains silicon and an element T, chosen from aluminum, iron, gallium or boron, such that the overall silicon/T atomic ratio is greater than 5. The dispersion of the group VIII metal is 50-100% and the macroscopic distribution is 0.7-1.3 inclusive. The catalyst has a mechanical crushing resistance, in a bed structure, of greater than 0.7 MPa. Independent claims are also included for the preparation of the catalyst and its use. |
