【Abstract】 Oil-soluble cobalt and nickel-based catalyst for hydropyrolysis of heavy oil was prepared with good thermal stability and stability for repeated use for viscosity reduction using petroleum sulfonate as emulsifier and toluene as hydrogen donor. The results showed that vicosity reduction rate of over 90% for Liaohe heavy oil was obtained at reaction temperature of 180 ℃ and catalyst dosage of 0.4%; Sidestream tests showed that the catalyst system could effectively reduce the viscosity of heavy oil, with viscosity reduction rate of over 74% at the initial period.更多还原
