The three-parallel-DAEM-reaction model was used to study the slow pyrolysis kinetics of rice straw based on thermogravimetric analysis (TGA) data. The kinetic parameters of the model were calculated using the pattern search method. A comparison between the predicted DTG data and experimental values showed good agreement. The influences of the kinetic parameters on the model for describing the experimental data of rice straw were analyzed by means of local parametric sensitivity analysis. The results indicated that the frequency factor and the mean value of the activation distribution for cellulose decomposition affect the model more strongly than other parameters, followed by the corresponding parameters for hemicellulose and lignin. The sensitivity of the model to the standard deviations of the activation energy distributions for all pseudocomponents is very slight.
采用三平行 DAEM 反应模型，基于热重分析（TGA）数据对稻草的慢速热解动力学进行了研究。利用模式搜索法计算了模型的动力学参数。通过比较预测的 DTG 数据与实验值，发现吻合良好。通过局部参数灵敏度分析，研究了动力学参数对模型描述稻草实验数据的影响。结果表明，纤维素分解的频率因子和活化分布均值比其他参数对模型的影响更大，其次是半纤维素和木质素的相应参数。模型对所有拟组分的活化能分布标准偏差的灵敏度非常低。
