Process for preparing highly active catalysts by incorporating a nickel compound and a heavy metal selected from the group consisting of molybdenum, tungsten and mixtures thereof into a specifically prepared alumina hydrogel. The final calcined catalysts have surface areas of at least 300 m<2>/g and at least 70% of the pore volume in pores having diameters less than 7 nm. |
