ABSTRACT:
Desulfurization and refining of aromatic hydrocarbon fraction containing organic sulfur compounds by catalytic hydrotreating can be performed with a high desulfurization rate (99 wt. % or higher) and without a significant loss (1 mol % or less) of the aromatic components.
The improved process is characterized by preliminary sulfurization treatment of the catalyst of Co--Mo system, Ni--Mo system or Ni--Co--Mo system using thiophenes, and hydrotreating of the aromatic hydrocarbon fraction using thus treated catalyst at a relatively high temperature.
