To develop effective water-soluble catalysts for aquathermolysis of heavy oil, in this paper, a series of complex was synthesized using phenyl hydroxamic acid and metallic chloride. The Ni(II) complex was characterized, and all the complexes were screened in aquathermolysis of heavy oil. The effects of water content and Ni(II) complex concentration on aquathermolysis were investigated. The effect of adding methanol as a reactant was examined and interpreted. With the catalyst and methanol, the reaction occurred at temperatures as low as 180℃. The viscosity of the product was also substantially reduced by the decomposition of the large hydrocarbon molecules.
