- Abstract
- Removal of sulfur by a transition metal is studied at temperatures of 300-350 degreesC. Among various metal sulifides tested, only metal sulfides of iron, cobalt, and nickel can remove sulfur fumes as they are transformed into disulfides in the presence of sulfur vapor. The disulfide form can be regenerated into FeS, CogS8, and Ni3S2, respectively, using hydrogen gas at 350-400 degreesC. These two reactions of deep sulfidation with sulfur and reduction with hydrogen can be utilized for the removal of sulfur fumes in a process stream and an emission gas.
