    Abstract: The present invention describes a method for hydrocracking and/or hydrotreating hydrocarbon-containing feeds using a catalyst comprising at least one hydro-dehydrogenizing metal selected from the group made up of group VIB and non-noble group VIII metals of the periodic table and a support comprising at least one zeolite having at least pore openings containing 12 oxygen atoms, modified by a) at least a stage of introducing at least one alkaline cation belonging to groups IA or IIA of the periodic table, b) a stage of treating said zeolite in the presence of at least one molecular compound containing at least one silicon atom, c) at least one stage of partial exchange of said alkaline cations by NH4+ cations in such a way that the proportion of alkaline cations remaining in the modified zeolite at the end of stage c) is such that the alkaline cation/aluminium molar ratio ranges between 0.2:1 and 0.01:1, and d) at least one thermal treatment stage.

    Abstract: A process for isomerizing a feed comprising at least one aromatic compound containing eight carbon atoms per molecule is carried out in the presence of a catalyst comprising at least one modified zeolite with structure type EUO, at least one binder and at least one metal from group VIII of the periodic table, said catalyst having been prepared using a process which comprises the following in succession: a) a step for treatment of a zeolite with structure type EUO in the presence of at least one molecular compound containing at least one silicon atom, during which said compound, with a diameter greater than the maximum pore opening diameter in said zeolite, is deposited in the gas phase on the outer surface of said zeolite; b) at least one heat treatment step; c) forming said zeolite with a binder; d) at least one step for introducing at least one metal from group VIII of the periodic table onto a support based on said modified and formed zeolite.
