摘　　要：通过热天平试验得出温度和高温下停留的时间都是影响ＣａＯ烧结和固硫性能的重要因素。９３０℃时，ＣａＯ固硫２０ｍｉｎ后其转变率可达８９％，而１１８５℃下煅烧２０ｍｉｎ后其最大固硫转变率仅为２６％；试图靠添加各种化合物配制复合固硫剂以改善ＣａＯ的烧结及固硫性能，试验结果表明。Through thermogravimetric experiment,this article shows that both temperature and resident time are all very important to the sintering of CaO.CaO under 930 ℃ has a changing rate of 89% after desulfurization of 20 minutes,but a changing rate of only 26% was found under 1 185 ℃.Moreover,by testing several compounds,the experiment gives the evidence that Ba(OH) 2 is a very promising additive to improve the desulfurisation property of CaO.
