【摘要】 研究了添加剂对型煤高温（１２００℃）固硫效果的影响．实验发现：ＭｇＯ对Ｃａ（ＯＨ）２固硫反应有较强促进作用；在钙基固硫型煤中同时加入硅酸盐和Ｆｅ２Ｏ３，可大大提高固硫效果，其ＸＲＤ图表明灰渣中形成了一些耐高温物质和 ＣａＳＯ４复盐（Ｃａ３Ａｌ６Ｏ１２·ＣａＳＯ４）；并得出 ＭＳ型煤的Ｃａ（ＯＨ）２和 ＭｇＯ加入摩尔比和固硫率关系的回归方程．更多还原

【Abstract】 To improve briquette sulphur capture efficiency above 1 200℃, some addi- tives are added into desulfurizers. Experiment results indicate that Ca(OH)2, MgO, feldspar and Fe2O3 working together can enhance sulphur capture efficiency. The sulphur capture efficiency achieves 79. 68% at 1200 ℃. The XRD figures show that high temperature stable compounds are formed. Furthermore, the suitable amount of MgO added into briquette is suggested in this pa-per.更多还原
