摘要
分别以花生壳和松木屑为原料在固定床上进行低温热解实验,探究热解温度对热解产物产率的影响。利用气相色谱-质谱联用仪(GC-MS)对热解所得生物油组分进行定性分析,并对生物油中的愈创木酚进行定量分析。结果表明:花生壳和松木屑热解过程中半焦的产率都随热解温度的升高而降低;生物油的产率都随热解温度的升高先升高后降低,且都在500℃达到最大值,最大产率分别为13.14%和20.41%;热解气体的产率都随热解温度的升高而升高。两种生物质热解生物油中各类组分的含量随热解温度的升高发生不同的变化,其中愈创木酚的含量都随热解温度的升高先升高后降低,并在400℃达到最大值。
In this study, fixed bed pyrolysis of peanut shell and pine sawdust were carried out in order to investigate the effects of pyrolysis temperature on products yields and distribution. The pyrolysis bio-oil characteristics and guaiacol content in bio-oil were analyzed by using gas chromatography- mass spectrometry （GC-MS）. The results showed that with increasing pyrolysis temperature, the char yield decreased. Peanut shell and pine sawdust pyrolysis bio-oil yield reached its maximum value of 13.14% and 20.41%, respectively, at 500 ℃. The gas yield increased monotonically with increasing temperature. Bio-oil was a mixture of various chemical compounds and its composition changed with varying pyrolysis temperature. The guaiacol concentration in bio-oil increased to its maximum at 400 ℃ and decreased thereafter.
