Abstract
To evaluate a co-processing process over Ni-Mo/Al2O3 catalyst in the ebullated-bed catalitic reactor such as H-COAL process, Taiheiyo-coal with tar sand bitu-men was liquefied in the presence of a high concentration of catalyst in an autoclave. Ex-perimental results showed that oil yields based on maf-feed and hydrogen consumption per unit oil yield of the co-processing were heigher than those of bitumen alone. The co-processing process seemed to be more economical than the hydrotreatment of tar sand bitu-men under the present conditions.
