Catalyst (I) comprises at least one modified zeolite EU-1 containing silicon atoms and aluminum atoms, at least one matrix and at least one group VIII metal of the periodic classification of elements, where the number of hexacoordinated aluminum atoms present in the modified zeolite is more than 20 wt.% of the total number of the aluminum atoms present in the modified zeolite EU-1. Independent claims are included for: (1) the preparation of (I) comprising: (a) synthesizing at least one zeolite EU-1 having a silicon/aluminum total atomic ratio of 5-100; (b) thermally treating the obtained zeolite EU-1 in the presence of water vapor to obtain modified zeolite EU-1; (c) setting the modified EU-1 zeolite with a matrix to form a modified zeolite support and (d) depositing at least one metal of the group VIII, where the order of carrying out the steps (c) and (d) is indifferent following the step (b); and (2) a process of isomerization of a fraction containing at least one aromatic compound containing eight carbon atoms per molecule, comprising contacting the aromatic fraction with (I), which is present in the catalytic reactor. |
