Hydrodesulfurization of coal tar pitch using Pt/Al2O3 and Pd/Al2O3 catalysts under mild conditions

Hydrodesulfurization of coal tar pitch using Pt/Al2O3 and Pd/Al2O3 catalysts under mild conditions

Hydrodesulfurization (HDS) of coal tar pitch (CTP) using Pt/Al2O3 and Pd/Al2O3 catalysts in tetrahydrofuran at 333 K and atmospheric pressure was investigated. The HDS of dibenzothiophene (DBT) proceeded over both the Pt and Pd catalysts under the mild conditions. The effects of polycyclic aromatic...

The effects of polycyclic aromatic hydrocarbons on the HDS of DBT were examined: a naphthalene ring suppressed the HDS, while a benzene ring did not. CTP underwent HDS as well as partial hydrogenation under the mild conditions. The Pt catalyst was more active than the Pd catalyst in the HDS of CTP. The sulfur content in CTP was reduced by over 50% through the HDS process.
