Process for hydrocracking a hydrocarbon charge comprises contacting the charge with a catalyst containing an amorphous or poorly crystallized matrix of the oxide type and an IM-5 zeolite, a hydrogenating-dehydrogenating element consisting of a group VIII or group VIB metal, and boron or silicon as promoter. Independent claims are also included for: (1) a catalyst for hydrocracking a hydrocarbon charge comprising 0.1-99.7 (wt.%) IM-5 zeolite, 0.1-60 hydrogenating-dehydrogenating metal, 0.1-99 matrix, 0.1-20 boron or silicon, 0-20 phosphorus, 0-20 group VIIA metal, 0-20 group VIIB metal, and 0-60 group VB; and (2) a process for the production of the catalyst comprising: (a) forming a precursor by molding a matrix, IM-5 zeolite, a group VIB metal, a group VIII metal, boron or silicon as promoter, phosphorus, and a group VIIA metal; (b) calcining at at least 150O> C; (c) impregnating the precursor obtained in (b) with a solution containing an element selected from a group VIIB, VB, VIII, VIB and VIIA element; (d) leaving the solid in a damp atmosphere at 10-120o> C; and (e) drying at 60-150o> C.
