| Abstract: | Limestone (CaCO 3) is a commonly-used calcium-based sorbent.The specific surface area of the porous decomposition product (CaO) has a great effect on the removal of SO 2/H 2S in combustion systems.Based on the reaction kinetics,the decomposition properties of limestone and the specific surface area of porous calcium oxide at various reaction temperatures,atmospheres and particle sizes are analyzed in this paper.The influences of CO 2 diffusion in porous product layer on decomposition,sintering of CaO during decomposition process and CO 2 on sintering were considered. |

| Keywords: | calcium-based sorbent CaCO 3 decomposition specific surface area of porous calcium oxide |
