Abstract

The present invention provides a method for separately removing mercaptans and hydrogen sulfide from a gas stream by passing the gas through a bed which includes iron oxide which catalyzes the formation of disulfides and trisulfides from mercaptans and also reacts with at least part of the hydrogen sulfide to form acid-stable solids; causing the di- and trisulfides to exit the bed in the gas phase; and removing and recovering the di- and trisulfides by adsorption or condensation.
Any remaining hydrogen sulfide may be scavenged from the gas stream by passage through a bed containing iron oxide similar to that used first above.
