【 摘 要 】

Hydrotreating with dispersed catalyst at ppm level can provide an efficient, economical alternative to upgrading heavy oil. In this study, slurry phase hydro-conversion process is used for viscosity reduction. Several reaction conditions have been investigated using highly dispersed catalyst. Residue conversion of extra-heavy oil up to 30% can meet the viscosity requirement for shipping, and the conversion of bitumen from oil sands up to 50% can meet the viscosity requirement for pipeline systems. These hydrogenation reactions with temperature ranging from 390°C to 420°C had higher liquid yield (from 98.5 wt% to 93.2 wt%). In addition, hydro-upgrading product contains lower concentrations of impurities compared to raw feed. Based on our research, an efficient and environmental friendly alternative upgrading process with low process temperature was proposed. The process uses dispersed catalyst for extra-heavy oil and oil sands bitumen treatment. Product properties meet the requirements for transfer and further application.
