Abstract:
1. A hydrocracking and/or hydrotreatment method, comprising catalyzing said method with a catalyst that comprises an active phase containing at least one hydro-dehydrogenizing element which is a VIB or non-noble group VIII element of the periodic table, alone or in an admixture, and a support comprising at least one zeolite modified according to a modification method comprising at least a) 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 the alkaline cations by NH 4 + 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, said zeolite having, prior to being modified, at least one series of channels whose opening is defined by a ring with 12 oxygen atoms (12MR), said catalyst being a sulfide phase catalyst.
