Abstract The present recommendations have been developed by the Kinetics Committee of the International Confederation for Thermal Analysis and Calorimetry (ICTAC). The recommendations provide guidance on kinetic analysis of multi-step processes as measured by thermal analysis methods such as thermogravimetry (TGA) and differential scanning calorimetry (DSC). Ways of detecting the multi-step kinetics are discussed first. Then, four different approaches to evaluation of kinetic parameters (the activation energy, the pre-exponential factor, and the reaction model) for individual steps are considered. The approaches considered include multi-step model-fitting as well as distributed reactivity, isoconversional, and deconvolution analyses. For each approach practical advice is offered on its effective usage. Due attention is also paid to the typical problems encountered and to the ways of resolving them. The objective of these recommendations is to help a non-expert with efficiently performing multi-step kinetic analysis and interpreting its results.

ICTAC 动力学委员会对多步动力学分析的建议

摘要 本建议由国际热分析和量热联合会 (ICTAC) 动力学委员会制定。这些建议为多步过程的动力学分析提供了指导，如通过热重分析 (TGA) 和差示扫描量热法 (DSC) 等热分析方法测量。首先讨论检测多步动力学的方法。然后，考虑了评估各个步骤的动力学参数（活化能、指数前因子和反应模型）的四种不同方法。考虑的方法包括多步模型拟合以及分布式反应性、等转化和解卷积分析。对于每种方法，都提供了有关其有效使用的实用建议。对遇到的典型问题和解决方法也给予了应有的关注。这些建议的目的是帮助非专家有效地执行多步动力学分析并解释其结果。
