摘要： Sulfur-containing petroleum oil feedstocks which include heavy hydrocarbon constituents undergo simultaneous desulfurization and hydroconversion by contacting and reacting such feedstocks with sodamide in the presence of hydrogen and at elevated temperatures. The mixture of reaction products resulting from the above procedure is separated to give a sodium sulfur salt by-product, and a petroleum oil product which has been substantially desulfurized and demetallized, as well as being significantly improved as indicated by a reduced Conradson carbon content and an increased API gravity relative to the feedstock. Sodamide is regenerated from the sodium sulfur salt by-product and can be recycled for reaction with additional feedstock.

摘要： Sulfur-containing petroleum oil feedstocks which include heavy hydrocarbons constituents undergo simultaneous desulfurization and hydroconversion by contacting such feedstocks with sodamide in the presence of hydrogen and at elevated temperatures. The mixture of reaction products resulting from the above procedure can be separated to give sodium sulfur salts and a petroleum oil product which has been substantially desulfurized and demetallized and significantly upgraded as demonstrated by a reduced Conradson carbon content and an increased API gravity.
摘要翻译： 包括重质烃成分的含硫石油原料通过在氢气存在下和高温下使这些原料与氯化钠接触而同时进行脱硫和加氢转化。 由上述程序产生的反应产物的混合物可以分离，得到硫酸钠盐和石油产品，其已基本上脱硫和脱金属化并显着升级，这通过降低的康拉逊碳含量和增加的API重力来证明。
