摘    要:对热学分析(TGA)实验测得的CaCO3分解反应动力学数据的解释曾一直采用了气固反应缩核模型的假设,这一简化处理方法导致了难以对实验中反应过程和输运现象间的关系作出定量描述,所获的动力学数据均具表观性质。作者基于气固反应结构模型观点提出了描述CaCO3分解反应等TGA实验的数学模型及相关数值模拟程序,并对文献记载的一组CaCO3分解动力学TGA实验数据作了新诠释。

关 键 词:碳酸钙 分解动力学 TGA实验 气固反应 计算机 数值模拟

Abstract:Nuclear shrinkage hypothesis of gas-solid reaction has always been used to explain the TGA test data of CaCO3 calcining reaction kinetics, relation between reaction process and transportation phenomena eann't be quantificationally described due to the simplified hypothsis, and so the results has apparent character. Based on gas-solid reaction structure model, maths model and the corresponding numeric simulator of isothermal TGA test data of CaCO3 calcining reaction. And give a new annotation to a set of CaCO3 calcining TGA test data from the literature.
Keywords:CaCO3 calcining reaction kinetics  TGA test: gas-solid reaction  computer numerical simulation
