In order to obtain the kinetic parameters during typical medical waste pyrolysis, the typical medical waste is pyrolysed in a micro-fluidised bed reactor. The gases evolved from the typical medical waste pyrolysis are analysed by a mass spectrometer, and only H, CH, CH, CH, CH, CH, CH and CH are observed. According to the gaseous product concentration profiles, the activation energies of gaseous formation are calculated based on the Friedman approach, and the average activation energies of H, CH, CH, CH, CH, CH, CH and CH formation during typical medical waste pyrolysis are in sequence as 65.10, 39.98, 35.17, 38.71, 40.75, 41.79, 58.57 and 63.95 kJ mol. Moreover, the activation energy with respect to the gases mixture formation is 52.70 kJ mol. Hence, it is concluded that the activation energy of typical medical waste pyrolysis is 52.70 kJ mol. The model-fitting method is used to determine the mechanism model of medical waste pyrolysis. The results indicate that the chemical reaction ( n = 1) model (G(x) = -ln(1-x)) is the optimum.
为了获得典型医疗废物热解过程中的动力学参数，在微流化床反应器中对典型医疗废物进行热解。通过质谱仪分析典型医疗废物热解产生的气体，仅观察到 H、CH、CH、CH、CH、CH、CH 和 CH。根据气态产物浓度分布，基于 Friedman 方法计算气态生成的活化能，典型医疗废物热解过程中 H、CH、CH、CH、CH、CH、CH 和 CH 生成的平均活化能依次为 65.10、39.98、35.17、38.71、40.75、41.79、58.57 和 63.95 kJ/mol。此外，气体混合物生成的活化能为 52.70 kJ/mol。因此，得出结论，典型医疗废物热解的活化能为 52.70 kJ/mol。采用模型拟合方法确定医疗废物热解的机理模型。结果表明，化学反应（n=1）模型（G(x)=-ln(1-x)）是最佳模型。
