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.
