Selective hydrodesulfurization of 4,6-dimethyldibenzothiophene in the dominant presence of naphthalene over hybrid CoMo/A{sub 2}O{sub 3} and Ru/Al{sub 2}Al{sub 2}O{sub 3} catalyst
- Kyush Univ., Kasuga, Fukuoka (Japan); and others
Hydrodesulfurization of 4,6-dimethyldibenzothiophene (4,6-DMDBT) in decane containing significant amount of naphthalene was examined over a hybrid of CoMo/Al{sub 2}O{sub 3} and Ru/Al{sub 2}O{sub 3} to design the selective hydrogenation and successive desulfurization of 4,6-DMDBT in aromatic moiety, and its activity was compared to those of CoMo/Al{sub 2}O{sub 3}, NiMo/Al{sub 2}O{sub 3} and Ru/Al{sub 2}O{sub 3} in their single use. HDS activity of 4,6-DMDBT over NiMo/Al{sub 2}O{sub 3} was inferior to CoMo/Al{sub 2}O{sub 3}, although that of highest hydrogenation activity for naphthalene. The hybrid showed the highest activity for HDS of 4,6-DMDBT among these catalysts without excess hydrogenation of nahthalene.
