The principal objective of this research is to evaluate catalysts for hydrotreating coal liquids. We evaluated the methylcarbazole hydrodenitrogenation (HDN), dibenzothiophene hydrodesulfurization (HDS) and dibenzofuran hydrodeoxygenation (HDO) activities of the supported carbide that was most active for the hydrotreatment of lower molecular weight heteroatom compounds. This catalyst was prepared in our laboratory and compared with commercial sulfide hydrotreatment catalysts
