摘　　要：采用热裂解-气相色谱质谱法对生物质焦油的热裂解特性进行了研究,分析了在1050℃和1300℃条件下裂解产物的情况:温度升高,裂解产物的总含量由1050℃的95.023%降至1300℃的83.373%,而其中11种主要裂解产物的相对含量却呈上升趋势,由59.027%升至64.645%;检出了焦油中含有氮硫等元素.实验结果与以往的实验存在较大差异,为全面了解焦油的性质提供了一定的依据.The pyrolysis characteristic of biomass tar has been investigated by pyrolysis gas chromatographymass spectroscopy, and the differences of production at the two different temperature in 1050℃ and 1300℃ have been analyzed. With the temperature raised,the contents of cracking productions reduced to 83. 373% from 95. 023%. But relative content of 11 main products increased, from 59.027% to 64.645%. Nitrogen and sulfur comtained in biomass tar has been examined by pyrolysis gas chromatography -mass spectroscopy. There is a greater difference to analyse the biomass tar from departed expriments,so it provides some basis for comprehensive understandingly the biomass tar.
