摘　　要：采用热分析-质谱联用(TA-MS)技术研究了四种城市生活固体垃圾的热解过程和热解气体种类。结果表明,PVC热解过程由一个阶段完成,香蕉皮和鸡骨头的热解过程分为两个阶段,烟头热解过程分为三个阶段;四种垃圾的热解均先是水份析出引起微小失重,随后是纤维素等大分子交联缩聚的快速热解阶段,它们的逸出气体主要是H2O、CO2、C3H3、C3H5、C3H6、C3H7、NO2、Cl、HCl等。Thermal analysis-mass spectrometry combined analysis method was used to study the pyrolysis process characteristics and the types of volatile gas of four typical solid waste in the city life including banana peels, chicken bones, cigarette butts, and PVC. The results showed that the pyrolysis process of PVC materials was finished in one step, and the pyrolysis process of banana peels,and chicken bones was finished in two steps. For the cigarette butts, the pyrolysis process is complex and the pyrolysis process can be divided into three steps. The pyrolysis process includs the slight weightlessness due to lossing of moisture, fast pyrolysis stage of cellulose and other macromolecules followed polycondensation and crosslinking which resulted in exothermic effect. The main escaped gas are H2O、CO2、C3H3、C3H5、C3H6、C3H7、NO2、Cl、HCl during pyrolysis process.
