【摘要】 在不同的煅烧温度和不同的硫酸盐化温度条件下，以ＭｇＯ为吸收剂，进行了固硫的实验研究。实验表明，菱镁矿（主要成分ＭｇＣＯ３）的煅烧温度越高，其煅烧产物ＭｇＯ的比表面积越小，因而ＭｇＯ硫酸盐化的初始反应速率越低。提高ＭｇＯ硫酸盐化的反应温度能够增加ＭｇＯ变成ＭｇＳＯ４的转化率。就最初反应速率而言，硫酸盐化反应温度的影响大于比表面积的影响。更多还原

【Abstract】 The characteristics of SO2 capture by MgO at different calcination and different sulphation temperatures have been studied experimentally It is found that the higher the calcination temperature of MgCO3,the smaller the specific surface area of MgO is,so is the initial reaction rate of sulphation of MgO As to the initial reaction rate,the influence of sulphation temperature is stronger than that of specific surface area of MgO更多还原
