Abstract
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,S is substantially suppressed and the formation of NaSH is promoted in the desulfurization process.
