Solvent effects on hydrodesulfurization (HDS) of dibenzothiophene (DBT) catalyzed by Co-Mo/Al[sub 2]O[sub 3] were investigated under deep hydrodesulfurization conditions. It was found that type of solvent affects HDS of DBT into biphenyl (BP). By contrast, the formation of cyclohexylbenzene (CHB) was scarcely affected by solvent such as xylene, decalin, tetralin, and n-hexadecane. From this result, it was suggested that desulfurization and hydrogenation proceed on different catalytic sites and that cyclohexylbenzene would be formed by hydrodesulfurization of hexahydrodibenzothiophene as well as hydrogenation of biphenyl.
