Abstract: The invention describes a catalyst comprising at least one hydro/dehydrogenating element chosen from the group formed by the elements from group VIB and from group VIII of the periodic table, alone or as a mixture, and a support comprising at least one zeolite and one amorphous silica-alumina, wherein the zeolite has an acid site distribution index (ASDI) of greater than 0.15 and a density of acid sites (determined by H/D exchange) of between 0.05 and 1 mmol/g, and wherein the support has a pore volume, measured by nitrogen porosimetry, developed within the pores with a diameter of between 6 nm and 11 nm, of less than 0.5 ml/g, a grain density, measured by mercury displacement under a pressure of 0.003 MPa, of greater than 0.93 g/ml, and a tapped packing density (TPD) of greater than 0.5 g/ml and less than 0.65 g/ml. A further subject of the present invention relates to the process for preparing said catalyst, comprising at least one step of preparing a silica-alumina gel by mixing a silica precursor with a specific alumina precursor, and to a process for hydrocracking a hydrocarbon feedstock in the presence of said catalyst.

Abstract: The invention describes a hydrocracking catalyst which is selective towards the naphtha cut and the hydrocracking process using said catalyst, said catalyst comprising at least one hydrogenating-dehydrogenating element chosen from the group formed by the elements of group VIB and the non-noble elements of group VIII of the Periodic Table, taken alone or as a mixture, and a support comprising at least one porous mineral matrix, a zeolite Y having an initial lattice parameter a0 of the unit cell of greater than 24.42 Å, and a zeolite beta, in which the weight ratio of said zeolite Y to said zeolite beta in the catalyst is strictly greater than 12.
