基于热重分析数据，采用三平行DAEM反应模型对稻草的慢速热解动力学进行了研究。采用模式搜索法计算了模型的动力学参数。预测DTG数据和实验值之间的比较显示出良好的一致性。采用局部参数敏感性分析方法，分析了动力学参数对描述稻草实验数据的模型的影响。结果表明，纤维素分解活化分布的频率因子和平均值对模型的影响最大，其次是半纤维素和木质素的相应参数。该模型的所有赝组分的活化能分布的标准偏差的敏感性是非常轻微的。(C)2012爱思唯尔有限公司保留所有权利。
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. (C) 2012 Elsevier Ltd. All rights reserved.
