ABSTRACT:
The nitrogen-containing and oxygen-containing contaminants of a mineral oil are converted to the corresponding sulfur compounds by contacting the oil with a fresh catalyst containing metals from Groups VB, VIB and VIII or a deactivated and metals contaminated hydrodesulfurization catalyst in the presence of hydrogen and hydrogen sulfide under conditions of elevated temperature and pressure.
