| 摘 要： | 从生物油中分离出热解木质素,对其基本特性进行了研究,同时与一种碱木素进行了对比.两种木质素的主要元素质量分数基本相同,但热解木质素中碳元素质量分数比碱木素稍高,氧元素质量分数稍低；红外光谱试验发现相对于碱木素,热解木质素中含有较少的醇羟基.热重试验结果表明,热解木质素在比较低的温度下表现出较大的质量损失速率,其热稳定性比碱木素差；热解气质联用试验显示出两种木质素的热解产物组成存在较大的差异,在250、550℃两个热解温度条件下热解木质素的热解产物中芳香族化合物含量都明显高于碱木素,而碱木素250℃的热解产物中主要组分为醇类物质,芳香族化合物质量分数较低,550℃的热解产物中芳香族化合物质量分数上升,醇类物质质量分数下降,同时产生大量的丙酮.

| Abstract: | Pyrolytic lignin was separated from bio-oil.The structure and pyrolysis characteristics of pyrolytic lignin were compared with an alkali lignin.The content of main elements in two kinds of lignin was the same level,but the content of carbon was higher and the content of oxygen was lower in pyrolytic lignin compared with alkali lignin.It was shown that alcoholic hydroxyl group in pyrolytic lignin was less than alkali lignin with Fourier transform infrared spectroscopy(FTIR) analysis.Thermogravimetric analysi... |
