【摘要】 废弃电池的回收利用是环境保护的重要课题之一 .废电池主要成分为石墨碳和MnO2 ,可以作为助燃剂在高炉喷煤工艺过程中使用 .由于MnO2 的分解速度直接影响其助燃作用 ,因而本文采用TG/DTA热分析方法研究了空气中MnO2 热分解的动力学参数 ,采用Kissinger法、Doyle Ozawa法及Coats Redfern方法确定了分解反应速率方程式 :dαdt=1.2 6× 10 2 6e- 43 90 0 0RT (1-α)更多还原

【Abstract】 How to reuse the waste battery is an important subject to environment protection The main composition of the waste battery is MnO 2, which can be used as support combustion agent for pulverized coal injecting into blast furnace The decomposition rate of MnO 2 has the main influence to the burning of coal , so the kinetics parameters of MnO 2 in the air are examined by the methods of TG/DTA in this paper Using the Kissinger, the Doyle Ozawa and the Coast Redfernt methods ,the reaction equation can be deduced as: d a d t=1.26×10 26 e 439 000 R T (1 α) 2更多还原
