Concept of the present study is to apply the oil agglomeration technique to pretreat coal for coprocessing with vacuum bottom of Athabasca bitumen. Coals used were Illinois, Montana and Wyoming. Pulverized coals were agglomerated with the bitumen. The parent coals and neat and deoiled agglomerates were liquefied in the presence of the bitumen as a solvent and FeS_2 as a catalyst under H_2 at 10MPa. Findings were as follows; the bitumen for agglomeration was effective for ash removal and recovery of coals were good over 95wt%, but not for the swelling.
