摘要
利用热重分析方法研究了钙基固硫剂的硫化反应特性,对影响钙利用率的几个因素进行了探讨。表明添加剂的加入改善了CaO的高温固硫性能,提高了固硫产物的热稳定性,使最佳固硫温度向高温区移动约100℃,热分析条件下钙利用率达65%。
This Raper introduces the sulfation characteristisa of calcium-based compound desulfrizer. The experiments are carried out by means of a thermogravimetic analyzer (TGA ) . The effect of several factors on calcium utilization ratio has been studied. The ex- periments results show that , additives can improve the sulfation characteristics of CaO in high temperature and to increase the thermal stability of desulfrization products. The opti- mum desulfrization temperature can be moved 100℃ towards high temperature region. The calcium utilization ratio can reach 65% under TGA condition.
