摘　　要：对ＣａＯ 经乙醇调质后的固硫特性进行了试验研究，详细研究了水合温度、乙醇／Ｈ２Ｏ 配比等因素对ＣａＯ 固硫率的影响并作了理论分析，探讨了调质过程的机理．提出了在乙醇调质ＣａＯ 后再添加少量金属化合物的方法，发现在１１００℃高温下仍可达７０ ％ 的固硫率．The SO\-2 removal characteristic of CaO modified by ethanol were studied experimentally.The hydration temperature,Ethanol/H\-2O ratio,combustion temperature and others were investigated systematically and analyzed theoretically.The desulphurization efficiency of the CaO would be about 80% when hydration temperature is 15℃,Ethanol/H\-2O ratio is 50%,combustion temperature is 1100℃ and Ca/S ratio is 3 0.It is also proposed that by the way of adding some metal compounds to CaO modified by ethanol,the desulphurization efficiency could be 67%—70% at combustion temperature 1100℃ as Ca/S ratio 2.0.The mechanisms of CaO treatment were also discussed in the thesis.
