ABSTRACT:
Heavy petroleum oils, preferably whole crude or residua, are desulfurized and upgraded by contacting the petroleum oil with sodium oxide in the presence of hydrogen at elevated temperatures. The resulting mixture comprising desulfurized petroleum oil and a dispersion of sodium salts, primarily sodium sulfide and sodium hydroxide, is separated by conventional means and sodium oxide is regenerated from the salts.
