Heteroatom-containing molecules in of South Banko coal liquid distillate were identified by the aid of gas chromatography with atomic emission detector. (GC-AED). Thiophenes and benzothiophenes were found to be the major sulfur compounds. Pyridines and anilines, and phenols were the major of nitrogen and oxygen compounds respectively. Heteroatom conversions on hydrotreatment over a series of NiMo catalyst are different. In hydrodesulfurization of CL, sulfur species were completely desulfurized by 60min at 360℃. However, hydrodenitrogenation and hydrodeoxygenation were more difficult even at severe conditions of 400℃. The higher surface area and acidity of catalysts showed the more heteroatom removal. Anilines are the most refractory species to convert among the nitrogen species. Hydrodeoxygenation of CL showed the difficulty in converting oxygen species at the present conditions and dibenzofuran was the most difficult to convert for oxygen species.
