Solvent effects on hydrodesulfurization (HDS) of benzothiophene (BT) and dibenzothiophene (DBT) catalyzed by Co-Mo/Al[sub 2]O[sub 3] were investigated under deep hydrodesulfurization conditions. Data for BT and DBT are arranged by the Langmuir-Hinshelwood equation. Activation energies of HDS of BT and DBT were approximately 21 and 24 kcal/mol respectively, in every solvent. Heats of adsorption of BT and DBT are both estimated to be 22 kcal/mol. Significant solvent effects were found under deep desulfurization conditions, and the values of heat of adsorption for various solvents were estimated from the K[sub sol] obtained. 14 refs., 3 figs., 3 tabs.
