文摘

To obtain clean liquid fuel, a study was conducted on upgrading shale oil by hydroconversion. Various W鈥揘i catalysts were synthesized and characterized using XRD, BET, TG, H₂-TPR, and NH₃-TPD methods. The effects of tungsten content and calcination temperature on the physicochemical properties and activity of catalysts were systematically investigated. W鈥揘i/Al₂O₃ with 15 wt % W-loading and 550 掳C calcination temperature was selected as the optimized catalyst. The product distribution of the primary aromatics in shale oil affected by hydrogenation, ring opening, and cracking reactions was discussed. Finally, key reaction parameters such as pressure, liquid hourly space velocity, and H₂/oil volume ratio were optimized. Characteristics of gasoline and diesel fractions were also measured.
