Description	The sulfidation rates of different limestone calcines were measured as weight gain in a differential, fixed-bed flow-through reactor at ambient pressure and high temperatures of up to 800 C. The increase in volume of the solid phase in the course of the reaction was explored by experiment and described by means of a simple structural model. The reacted solids remain fairly porous (~20%) even when they are practically converted into CaS. On petrographic examination, eight specimens of commercially exploited limestones were tested to determine their capacity to react with H2S. The calcines prepared from very fine-grained carbonate rocks were found as the most efficient sorbents. Having amassed time-resolved conversion data on CaO sulfidation, we developed a simple correlation. It allows the estimation of the reaction rate as a function of temperature, concentration of hydrogen sulfide in the gas phase, and conversion of the solids. The proposed kinetic equation can readily be employed in modeling and si The sulfidation rates of different limestone calcines were measured as weight gain in a differential, fixed-bed flow-through reactor at ambient pressure and high temperatures of up to 800 C.
