【Abstract】 The impregnating solution of Mo-Ni-P prepared by using MoO3·H2O, NiCO3, H3PO4 without the impurities of Na+ and NH+ is better than that made from MoO3, 2NiO(OH)2 ·Ni/CO3 and H3PO4 and no precipitation is found for being kept for a long time. According to the results of amonia-dissolving and XRD experiments, a solubility threshold of Mo or Ni component on the support is found and the Mo/Ni mole ratio is 0. 8:1 after ammonia-dissolving. Component P can suppress the interaction of the support with the compound of Mo and Ni on the surface of the support. The TPR results reveal that the suppression of the reduction of NiO by component P is reduced by the interaction of P with support, and the reduction temperature of MoO3 can also be decreased by the inrteraction between the compound of Mo and support. In addition, a suitable load amount of Mo-Ni-P impregnating solution is given.更多还原
