METHOD OF REMOVING SULFUR OXIDE FROM GAS BY USING ABSORBING MATERIAL CAPABLE OF BEING REGENERATED BY REACTION WITH HYDROGEN SULFIDE

摘要

The invention concerns a process for removing sulfur oxides and particularly sulfur dioxide contained in such gases as industrial fumes, wherein said gas is contacted with a solid absorbent containing magnesium oxide and at least one group VIII noble metal, in such conditions that the sulfur oxides are mainly fixed as magnesium sulfate, and then the used solid absorbent is regenerated by contact with a hydrogen sulfide-containing reducing gas.
