| 目的 研究胶黏剂对木质包装材料快速热解特性的影响。方法 在固定床反应器装置上进行快速热解实验， 对比胶黏剂、 实木木材和刨花板在不同温度下热解产物的产率。在热解气相色谱质谱联用系统上进行快速热解和产物分析， 对比胶黏剂、 实木木材和刨花板热解产物分布特性， 对比在不同温度和不同胶黏剂含量下刨花板快速热解产物的分布。结果 胶黏剂对刨花板热解油的生成有促进作用， 这种促进作用随温度升高先增强后减弱， 在550 ℃时达到最大值； 刨花板热解产物中氮杂环化合物的种类和含量比木材热解产物要高， 酸类和酚类物质的含量也有不同程度的提高， 而胺、 醇、 醛、酯、 糖等成分有不同程度的降低。结论 胶黏剂对刨花板整体热解趋势和产物种类影响不大， 但对热解油产量和产物分布的影响较大， 液相产物中含氮产物的种类、 含量和分布受胶黏剂含量和温度的影响比较明显。 |

| The aim of this work was to study the effects of UF resin on the fast pyrolysis characteristics of waste wood packaging materials. Fast pyrolysis experiments were conducted on a fixed bed reactor and a py-GC/MS system specifically. The yield and products distribution in liquid product from UF resin, wood and particle board were compared as well as products distribution at different temperatures and with different resin amount. UF resin promoted the production of pyrolysis oil during fast pyrolysis of particle board. This effect increased with temperature, reached a peak value at 550 ℃, and decreased afterwards. The types and contents of nitrogenous products in liquid phase product obtained by fast pyrolysis of particle board was higher than those of wood. The contents of acids and phenols were also increased while the contents of ammonias, alcohols, aldehydes, esters and sugars were decreased to different extents. In conclusion, UF resin had little effect on the decomposition profile and types of products during fast pyrolysis of particle board, but showed a relatively large effect on the yield of pyrolysis oil and products distribution. The types, contents and distribution of nitrogenous products in liquid phase product were obviously affected by the pyrolysis temperature and content of UF resin in waste packaging wood materials. |
