Abstract The invented catalyst possesses low active metal content and centrallized pore distribution, and has excellent residual oil hydrodenitrification and hydrogenation carbon residue removing activity. Its preparation is characterized by that in the course of kneading monohydrate aluminium hydroxide the nickel-containing metal salt can be mixed so as to provide nickel content required for catalyst, then a neutral solution is added, and mixing, then an acid solution is added, and kneaded, so that Al2O3 carrier containing nickel and silicone can be prepared, then it can be once carried on the molybdenum-containing compound by means of impregnation method.
