摘要
本文建立了确定固态热分解非等温反应机制的动力学模型,根据该模型研究了CaCO_3分解的反应动力学。结果表明;不同升温速度条件下CaCO_3分解受不同的反应机制控制.同时;随着升温速度提高.CaCO_3分解的活化能降低。
The kinetic model for determining the non- isothesmal
mechanism of decomposition reaction of solid has been proposed.According to this, the reaction kinetics of the decomposition of calcium carbonate has been investigated. It has been shown that the decomposition of calcium carbonate in the conditon of different rate of heating-up is controlled by different reaction mechanism. Meanwhile, the active energy of the decompostion of condition carbonate is decreased with the increment in the rate of heating-up.
