The invention relates to a method of preparing a catalytic composition comprising at least one non-noble metal from group VIII and at least one metal from group VIB of the periodic table. The invention also relates to the catalytic composition thus produced, which has a high specific activity in reactions involving the hydroprocessing of light and intermediate fractions, preferably in reactions involving the hydrotreatment of hydrocarbon streams, including hydrodesulphurisation (HDS), hydrodenitrogenation (HDN) and hydro-dearomatisation (HDA).
