Sorbents of calcined limestone and oyster particles having a diameter of about 0.63㎜ were exposed to simulated fuel gases containing 5000ppm H2S for temperatures ranging from 600 to 800℃ in a TGA (Thermalgravimetric analyzer). The reaction between CaO and H2S proceeds via an unreacted shrinking core mechanism. The sulfidation rate is likely to be controlled primarily by countercurrent diffusion through the product layer of calcium sulfde(CaS) formed. The kinetics of the sorption of H2S by CaO is sensitive to the reaction temperature and particle size, and the reaction rate of oyster was faster than the calcined limestone.
