A B S T R A C T PROCESS FOR PREPARING SUPPORTED HYDRO- CONVERSION CATALYSTS AND CATALYSTS THUS PREPARED A process for preparing supported hydroconversion catalysts containing one each of Mb or W and of Co and/or Ni incorporated into a suitable support by preparing an aqueous impregnating solution having a pH in the range of 0.7-2.7 comprising mixing at least one each of a compound of molybdenum or tungsten and a compound of cobalt and/or nickel, a stabilizing amount of 0.2-1.0 mole of phosphorous per mole Mo or W, and from 2-6 %w, basis support, of a suitable soluble amine compound. A suitable support is then impregnated with said solution followed by drying and calcining. The catalysts obtained demonstrate significantly increased hydrodenitrification activity.
