| 摘 要： | 水合煅烧是改善CaO脱硫性能的一种有效方式，从改变水钙比和煅烧温度两个影响因素出发，实验研究了高温煅烧后CaO颗粒孔隙特性的变化，并结合TGA实验测定了水合煅烧CaO的脱硫性能的改变效果，最后从孔隙内液体相变析出的膨化作用与毛细作用两个角度解释了实验现象。

| Abstract: | Fast and/or explosive evaporation in pores was employed to reconstruct CaO micro\|pore structure by hydrating and calcining. The experimental results shown that both micro\|scale configuration and pore distribution of hydrated CaO were greatly altered and highly dependent upon the calcining temperature and the ratio of water and CaO. TGA experiment was conducted to analyze the effect of reconstructed CaO pore behavior on desulfurization. |

| Keywords: | pore size distribution hydration CaO TGA |
