In this study, heavy oils were separated from coal liquid and upgraded by 2 different methods; (I) dilution with hexane for separation of asphaltene and (II) extraction by CUCI_2-2H_2O for removal of nitrogen compounds. Upgraded heavy oils were combined again with coal liquid distillates and hydrotreated in a batch-type autoclave with commercial NiW/Al_2O_3 catalyst at 350℃ for 2-4h under H_2 initial pressure of 5MPa. The results showed that pre-upgrading of heavy oils considerably increases whole coal liquid hydrodenitrogenation rate and reduces nitrogen content of products.
