Abstract:
     This invention relates to an acidic co-impregnating liquor used for preparing highly active hydrogenation -refined catalyst. It is a beteropolygcid containing Mo, Ni, a kind of alkaline tungstate (preferably ammonium salt) or highly water soluble tungstic acid and phosphoric acid. Mo-Ni-W-P catalyst prepared by impregnating Al2O3 carrier with said Co-impregnating liguor possesses a hydrogenation-denitrification actionty higher than commercial Mo-Ni-P catalyst by 35% for petroleum distillates. At the same time, the operating pressure is lower and the impregnation is by one-step. It overcomes the disadvantages involved is two-step impregnation which is required by introducing the third metal component on the conventional Mo-Ni-P catalyst. This invention possesses a definite benefit of energysaving.
