Effects of Solvents in Deep Desulfurization of Benzothiophene and Dibenzothiophene

Abstract Solvent effects on hydrodesulfurization of benzothiophene (BT) and dibenzothiophene (DBT) catalyzed by Co–Mo/Al2O3 were investigated under deep desulfurization conditions by using Langmuir-Hinshelwood (L–H) rate law. Solvents affected heats of adsorption of thiophenes rather than activation energy of HDS. Activation energies of HDS and heats of adsorption of thiophenes and solvents were estimated from the kinetic data.
