Two series of ten transition metal complexes were prepared as the catalysts for the catalytic aquathermolysis of heavy oil at relatively low temperature. In this reaction system, the dosage of water can affect the aquathermolysis efficiency, and the proper mass fraction of water/oil is 0.3. Some complexes can catalyze the aquathermolysis effectively at 180 ℃, in which N₅ catalyst is the most effective one to drop the pour point with 11.4 ℃, while N₂ and N₅ catalysts are the most effective ones to reduce the viscosity by more than 70%. The proper dosage of N₅ catalyst in this reaction system is 0.5%. TG and GC analysis show that the light components increase remarkably after the aquathermolysis.
