摘　　要：在温度为900℃下,采用热裂解仪,并结合气相色谱质谱联用技术,对城市垃圾热解产物的主要热解成分和分子量进行定性分析;为了保证实验数据的精确性,主要选用了热解产物的相似度在90%以上的物质。结果表明,城市垃圾在900℃温度下热解的产物主要有烷烃类、烯烃类、酸类、酯类和酚、呋喃类以及其他,其中垃圾中的厨余成分含有的热解产物有16种,废纸屑中含有19种,木废料中含有16种,塑料中含有26种,纤维织物中含有27种。通过对城市垃圾热解产物的GC-MS分析,了解城市垃圾的热解机理,并为城市垃圾的能源化利用提供依据。At a temperature of 900 ℃,combined with gas chromatography mass spectrometry,qualitative analysis for urban waste pyrolysis products and the molecular weight of pyrolysis was taken. In order to ensure the accuracy experimental data,pyrolysis products in more than 90% similarity of substance were mainly selected. The results showed that,the products of urban waste pyrolysis at temperature 900 ℃ were mainly organic acids,aldehydes,alkanes,phenols and soon. The thermal decomposition products of the kitchen waste component in the garbage contains 16 species,wastepaper contains 19 kinds,wood waste contains 16 kinds,plastic contains 26 kinds,fabric contains 27 kinds.Through the urban waste pyrolysis products by GC-MS analysis,to understand the mechanism of thermal decomposition of urban waste,the basis for energy utilization of urban waste was provided.
