| 摘 要： | 利用热重分析仪和傅里叶红外光谱仪对煤与木屑混合物在惰性气氛中进行了共热解研究,考察煤阶及煤与生物质掺混比例对热解过程的影响.结果表明,煤与木屑共热解特性并不是单独煤和单独木屑热解特性的简单叠加;高阶煤与生物质共热解更有利于协同反应的发生.通过对红外吸收光谱的分析发现,木屑与不同煤化程度煤共热解析出气体的成分和含量也不同,说明煤阶对煤与生物质共热解的气态产物有明显影响,也从侧面揭示了混合物热解过程中煤与木屑之间发生了相互作用.

| Abstract: | The pyrolysis characteristics of the coals and sawdust in an inertia atmosphere were investigated using a thermo-gravimetric apparatus with a on-line infrared-spectrum analyzer. The influence of blend ratio and coal rank on the pyrolysis of coal with sawdust blends was examined. The experimental results show that the pyrolysis characteristics of coal with sawdust blends are not similar to that of every single sample addition of single coal with single sawdust. The high rank coal with sawdust is more benefic... |
