Abstract
Removing sulfur oxide and carbon monoxide in a flue gas stream by combusting fuel in the combustor with a reduced amount of oxygen to partially convert carbon monoxide therein to carbon dioxide and sufficient to convert all sulfur-containing species in the flue gas stream to sulfur oxide and thus form a sulfur oxide enriched gas stream having between at least about 500 ppm carbon monoxide. 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 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.
