ABSTRACT:
Removing sulfur oxide, carbon monoxide and nitrogen oxide in a flue gas stream by combusting fuel in the combustor with a reduced amount of oxygen to convert all sulfur-containing species in the flue gas stream to sulfur oxide, and to partially convert carbon monoxide therein to carbon dioxide, thus forming a sulfur oxide enriched gas stream having between at least about 500 ppm carbon monoxide and a consequential reduced amount of nitrogen oxide. The sulfur oxide enriched gas stream is contacted with a solid adsorbent bed for adsorbing the sulfur oxides in the form of inorganic sulfates and/or sulfur oxides. The solid adsorbent contains a catalytic oxidation promoter for oxidizing the carbon monoxide gas stream to carbon dioxide, thus forming a sulfur oxide and carbon monoxide depleted stream with the consequential reduced amount of nitrogen oxide for disposal. The adsorbent bed is then contacted with a reducing gas stream for regenerating the adsorbent bed to form a hydrogen sulfide and/or sulfur dioxide bearing stream.
