| 摘 要： | 利用TGA和TPO对碳烟进行燃烧特性和动力学分析.研究表明,碳烟氧化过程主要发生了失水干燥、可溶性有机成分(SOF)氧化和固体碳氧化的变化.碳烟中水的质量分数约为3%,SOF质量分数约为40%,固体碳质餐分数约为25%,金属灰分质馈分数约为4%,堇青石材料和铁锈质量分数约为16%,硫化物等其他成分质量分数约为2%.随着升温速率的增加,TGA各曲线向高温区移动,对应的最大峰值温度升高,热滞后现象加重.通过Redhead法对TGA和TPO数据进行动力学分析,得出碳烟的活化能为160～170 kJ/mol.

| Abstract: | The combustion characteristics and dynamic behaviors of soot have been studied by using TGA and TPO.The results show three distinct stages of soot in the process of TGA,including dehydration,oxidation of solvent organic fraction(SOF) and oxidation of solid carbon.The contents of water,SOF,solid carbon,metals ash,cordierite and rust,other components in the soot are 3%,40%,25%,4%,16%,2%,respectively.With the increase of heating-rate,the curves of TGA and temperature move to the high-temperature zone and the m... |
