ABSTRACT:
Sulfur-containing petroleum oil feedstocks which include heavy constituents undergo both desulfurization and hydroconversion by contacting such feedstocks with sodium hydride in the presence of hydrogen, at elevated temperatures. The mixture of reaction products resulting from the above procedure can be separated to give a petroleum oil product which has been desulfurized and demetallized and has a reduced Conradson carbon content and an increased API gravity relative to the feedstock, and a by-product of sodium sulfide salt.
