摘　　要：对城市生活垃圾衍生燃料 (RDF)进行压模成型处理 ,改变其空间结构如比表面积、孔结构等 ,然后在TB 1型热天平中测试不同温度下的热解TG曲线 ,分析各种动力学参数 ,得出RDF性质、空间结构对热解反应速率、活化能、指前因子等动力学参数的影响规律 .试验结果表明 ,压型试样的反应速率明显低于未压型试样 ,最佳热解反应温度段为 5 5 0℃～ 65 0℃ .部分压型试样的活化能和指前因子之间存在着补偿效应 ,虽然压型试样的活化能有所减少 ,但指前因子有约 1The micropore surface area and micropore structure of refuse derived fuel (RDF) was changed by compression treatment. Thermogravimetric curves can be obtained at different pyrolysis temperatures, to estimate some of the kinetic parameters of different samples. A number of data collected and analysis was presented in the paper, together with the rules of kinetic parameters and discussion on the influence of the character of RDF's micropore structure. The reaction rates of the compressed samples were much lower than those of the uncompressed samples. And the optimal reaction temperature was 550℃～650℃. There was a compensation effect between activation energy and the Arrhenius parameters of some compressed samples. The activation energy decreases and the Arrhenius parameters are ten times less than uncompressed samples.
