| 摘 要： | 本文采用热失重、热解气相色谱质谱联用等分析方法,分析了蔗渣磨木木素的热化学特性,同时对蔗渣磨木木素快速热解过程进行了初步研究.蔗渣磨木木素在隋性气体氛围下,热化学裂解形成大量含苯环的木素基本结构单元衍生物,部分进一步降解成小分子化合物.其热化学降解特征表现为自由基反应模式. |
| 关 键 词： | 蔗渣 木素 热解特性 热解色谱质谱 |

| Abstract: | The thermochemical characteristics and the pyrolysis of mill wood lignin(MWL) of bagasse in nitrogen were investigated with thermogravimetric analysis(TGA) reaction system and combined Pyrolysis Gas Chromatography Mass Spectrometry (Py GC MS).The result indicated that MWL was degraded to lots of basic structure unit ramifications contained phenyl of lignin,some of which were decomposed to compound of small molecular weight.Its pyrolysis model hold free reaction characteristics. |
| Keywords: | lignin pyrolysis characteristics Py GC MS |
