  Abstract

Sulfur emission control in coal gasification plants implies the removal of HaS from the fuel gas in the gas clean-up system. In this study, the effects of particle size of sorbents, temperature of sulfidation and sorbent characteristics on the H2S removal efficiency of manganese ore were investigated. Experimental results showed that the removal efficiency of H2S was optimum when the temperature was about 700℃. And that the smaller particle size, the higher the H2S removal efficiency, but that was not effective very much. As the temperature increases, the reactivity of sorbents has lowered because agglomeration of sorbents increased the intraparticle transport resistance. This phenomenon was cofirmed by SEM photographs. The equilibrium (PH2O/PH2O) obtained by experiments is represented as a log (PH2O/ PH2S) = 5653/T - 3.7909. It was showed that the natural manganese ore could be used as a sorbent because its capacity for H2S removal is equivalent to the eariler developed sorbents.
