| 摘 要： | 循环镁法烟气脱硫工艺是利用Mg(OH)2浆液吸收烟气中的SO2,脱硫副产物经过热解还原为Mgo,再次制浆从而使之被循环利用.继讨论了MgSO3的最佳热解条件后,本文旨在进一步研究MgSO4的热解条件,以便寻找回收脱硫副产物的最佳条件.优化各个因素后得到MgSO2的最佳热解温度为850℃,热解时间为2h.热解产物通过X-衍射、柠檬酸法CAA法进行分析,得出该条件下MgSO4的分解率、产物MgO的纯度与反应活性最佳.

| Abstract: | Magnesium hydroxide slurry was used for sulfur dioxide absorption in regenerative magnesia scrubbing fuel gas desulfurization (FGD) system. Magnesia was regenerated from desulfurization by-products through pyrolysis process and was applied in the system as resources recycling. Based on our former study on pyrolysis of MgSO3, this study focuses on discussions of pyrolysis condition of MgSO4 in order to find an appropriate recycling way of FGD by-products. An optimal magnesia yield was gained under a temperat... |
