ABSTRACT:
Sulfur dioxide is removed from flue gases by contacting the flue gas at elevated temperature with a sorbent comprising a shaped refractory substrate of low surface area and an adherent oxide film impregnated with a transition metal or metal oxide which is selective for the removal of sulfur oxide from gas mixtures on the external surface of the substrate. A technique for laying down the adherent oxide film on the refractory substrate is also disclosed.
