ABSTRACT:
A method for desulfurizing gases in which the sulfur is mainly in the form of hydrogen sulfide by reacting with one of the forms of cerium oxide with the formation of a cerium-oxygen-sulfur compound, which method can be conducted at temperatures as high as the lowest melting point of either the cerium oxides or cerium-oxygen-sulfur compounds formed by the reactions. The method also includes a definition of the temperature necessary for the regeneration of the cerium-oxygen-sulfur compounds back to cerium oxide which is capable of again reacting with the hydrogen sulfide of the gases being desulfurized whereby the emission of sulfur from the combustion of sulfur containing hydrocarbons is reduced to a level below that attainable with any other method when operated at the same high temperatures.
