【摘要】 采用热分析方法研究了菱镁矿、高岭石分解过程动力学参数活化能Ｅ、反应级数ｎ，由ＴＧ、ＤＴＡ两种实验数据，用Ｃｏａｔｓ，Ｒｅｄｆｅｒｎ和Ｋｉｓｓｉｎｇｅｒ计算方法对比计算，从而得出高岭石活化能Ｅ＝１８８．７１２ｋＪ／ｍｏｌ，菱镁矿活化能Ｅ＝１８０．８２８ｋＪ／ｍｏｌ。更多还原

【Abstract】 The activation energies and the reaction orders n of magnesite and kaolinite are calculated, with Coats,Redfern and Kissinger methods, from the TG and DTA curves at different heating rates. The activation energy of kaolinite is E =188.712 kg/mol, and that of magnesite is E =180.828 kg/mol.更多还原
