Calculation of kinetic parameters from thermogravimetric data

摘要

摘要: 用热重(TG)法和微分热重(DTG)法,对草酸钙(CaC2O4·H2O)和乙酸钙(CH3COONa·3H2O)的热分解反应进行动力学分析,假设分解反应符合简单动力学方程式,速率常数符合Arrhenius型,并忽略温度对活化能的影响,由此给出热分解过程的动力学参数如反应级数(n)、活化能(E)等.

Abstract: The decomposition kinetics of CaC2O4·H2O and CH3COONa·3H2O has been studied by using TG and DTG technique.Kinetic parameters such as order of reaction (n) and activation energy (E) have been obtained.
