Abstract
A process for the removal of sulfur oxides from a gas which comprises (a) contacting the sulfur oxide-containing gas with at least one of certain metal, oxygen-containing components, e.g., modified perovskite-type components, at conditions effective to associate at least a portion of the sulfur oxides with the component to reduce the amount of sulfur oxides in the gas; and (b) contacting the component containing associated sulfur oxides at conditions effective to reduce the amount of sulfur associated with the component.
