Abstract

The selective hydrodesulfurization (HDS) reaction of 4,6-dimethyldibenzothiophene (4,6-DMDBT) in decane containing a dominant amount of naphthalene was examined over blends of CoMo/Al₂O₃ and Ru/Al₂O₃, and their activity was compared to those of CoMo, NiMo, and Ru/ Al₂O₃ in their single use. The blend exhibited an excellent activity for HDS of 4,6-DMDBT through its selective hydrogenation without excess hydrogenation of the aromatic partner. NiMo/Al₂O₃ and CoMo/Al₂O₃ examined in the present study were inferior to the blend for the HDS of 4,6-DMDBT, because the hydrogenation activity of the first catalyst is toward the aromatic partner while the second catalyst is inferior in the hydrogenation activity for 4,6-DMDBT.
