ABSTRACT:
A method and system useful for the removal of contaminants such as sulfur oxides from waste gas streams using a graded-bed system is disclosed. The graded-bed system uses beds with solid sorbents of two or more particle sizes in separate sections of the bed. In one embodiment, the solid sorbents are arranged so that the larger sorbent particles are disposed in the entrance region of the graded-bed system. In operation, a waste gas stream is passed over and through the solid sorbents so that contaminants, such as sulfur oxides and/or nitrogen oxides are adsorbed. The sorbent bed is then contacted with a reducing gas to desorb the sulfur oxides.
