Sulfur-containing petroleum feeds are desulfurized by contacting the feeds with staged addition of sodium metal at temperatures of at least about 250° C. in the presence of excess hydrogen to sodium metal. The formation of Na 2 S is substantially suppressed and the formation of NaSH is promoted in the desulfurization process.

Desulfurization at a glance. Desulfurization is the process of using hydrogen gas to reduce the sulfur content in hydrocarbons thus reducing the emissions of sulfur oxides which are responsible for acid rain. Countries across the globe have increasingly strict regulations in place to limit the sulfur content in fuels.

Nov 30, 2019· Desulfurization of molten steel is one of important reactions in ironmaking and steelmaking. Sulfur (S) in the molten steel is removed into a molten slag contacting the steel during the reaction. Many researchers have investigated on sulfide capacity of molten slags that is a useful concept to understand the desulfurization of the molten steel.

New requirements for very low sulfur content (10 ppm) in liquid motor fuels demand novel approaches for ultra-deep desulfurization. For production of near-zero-sulfur diesel and low-sulfur fuel oil, removal of refractory sulfur compounds, like 4,6-dimethyldibenzothiophene and other alkyl-substituted thiophene derivatives, is necessary.
