| 摘 要： | 石灰石是燃煤流化床中常用的钙基脱硫剂．选择和添加合适的助剂以改善石灰石颗粒的孔结构是提高ＣａＯ转化率和脱硫效率的一个重要途径．本文借助于压汞仪和ＳＥＭ扫描电镜从孔结构参数和ＣａＯ颗粒表面的可视化两个方面研究了几种特定的添加剂对煅烧石灰石孔结构的影响．图４，表２，参４

| Abstract: | Limestone is usually used as desulferization agent in coal fluidized bed.The pore structure of calcined limestone is an important factor to limit the SO 2 diffusion. In order to get higher dsulferization rate.Autoscan 3.3 mercury porosimeter is applied for studying pore structure parameters of calcined limestone. SEM photograghes show CaO grains' surface structure. The results indicates various additives have various functions on the pore structure.4figs.,2tabs.,4refs. |
