| 摘 要： | 研究制备了两类吸着剂，一类在Ｃａ（ＯＨ）２中混入易潮解性盐和碱，另一类是Ｃａ（ＯＨ）２与燃煤飞灰的水合物。在积分式固定床反应器系统的脱硫活性测试表明，添加剂的吸湿作用加速了表面反应，添加剂与Ｃａ（ＯＨ）２的湿混干燥物活性较纯Ｃａ（ＯＨ）２可提高１～２５倍；飞灰和Ｃａ（ＯＨ）２的水合物可使活性提高达５倍，利用飞灰增强钙基脱硫剂的活性是可能且有效的途径。

| Abstract: | Two classes of sorbent were prepared first, one was the pure Ca(OH) 2 mixing with the deliquescent additives, the other was the hydrates of Ca(OH) 2 and coal fired fly ash. Then, the evaluation on their reactivity with SO 2 was conducted in an integrated fixed bed reactor system. The results showed that the addition of deliquescent compounds enhanced the reactivity by 1～ 2 5 times, and the hydrates of calcium and fly ash had the reactivity up to 5 times higher than that of pure calcium, which proven to be an effective way to enhance the utilization of dry calcium based sorbents. |
