Process for preparing highly active hydrotreating catalysts by incorporating an element selected from the group consisting of nickel, cobalt and mixtures thereof, and a heavy metal selected from the group consisting of molybdenum, tungsten and mixtures thereof (with a stabilizing amount of phosphorus) into a (phosphated) alumina hydrogel support. The final calcined catalysts have surface areas of at least 300 m<2>/g, at least 20% of the pore volume in pores having diameters greater than 35 nm and at least 20% of the pore volume in pores having diameters less than 7 nm.
