摘　　要：针对城市固体废弃物(MSW)高效能源化及产物高值化利用的发展需求,利用管式炉实验及色质联用(GC-MS)分析仪对典型MSW进行热解特性研究,探索了热解产物产率和组分特性的变化规律.实验结果表明:热解温度对热解过程有较大的影响,废纸板、废轮胎和PVC的产油率分别在热解温度为550,650和700℃时达到最大值31.27%,22.9%和19.73%;催化剂HY的加入对废纸板热解油品质的提高效果不佳,但对废轮胎和PVC热解油品质的提高效果较好.与单组分热解油相比,混合热解油更复杂,酸类、酚类等化合物的质量分数减少,酯类、杂环类等化合物的质量分数增加,使混合热解油稳定性增强、腐蚀性减弱,品质得到明显提升,为其在化工和能源方面的综合利用提供了基础.According to the development requirement of high-efficient energy and high-value utiliza- tion of municipal solid waste （ MSW）, a tubular furnace reactor and the gas chromatography-mass spectrometry （GC-MS） are used to research the pyrolysis characteristics of the typical MSW. The yields, compositional properties of the pyrolysis products are investigated. The experimental results show that the pyrolysis temperature significantly influences the pyrolysis process. When the pyrolysis temperatures are 550, 650 and 700 ~C, the maximized oil yields of the cardboard, waste tyre and PVC are about 31.27% ,22.9% and 19.73%, respectively. The catalytic effect of the catalyst HY on the quality improvement of cardboard pyrolysis oil is not obvious, while it is effective for the quality of rubber and PVC pyrolysis oil. The pyrolysis oils from the mixed MSW are more complex than those from the single MSW. In the former, the mass percentage of the acids and phenols are re- duced; the mass percentage of the ester and heterocyclic are increased; the oil stability is improved and corrosivity is weakened. The quality of the mixed MSW is obviously improved, which provides a basis for its comprehensive utilization in chemical and energy industry.
