热分析法研究矿物分解过程动力学
THERMAL ANALYSIS OF THE KINETICS OF DECOMPOSITION OF MINERALS
【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。
【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.
