硫酸分解磷矿第一阶段反应动力学研究

Study on reaction kineticsin the first-stage of decomposing phosphate rock with sulfuric acid

对硫酸分解磷矿粉的第一阶段反应进行了动力学研究,通过对实验数据的分析,证明此阶段反应为一级反应。反应速率常数与温度的关系符合阿累尼乌斯方程,活化能Ea为8.65kJ/mol。

<Abstrcat>The reaction kinetics in the first-stage of decomposing phosphate rock with sulfuric acid was studied. It was proved by the experiment that the first-stage reaction was a first-order reaction. The relationship between temperature and reaction velocity constant accorded with arrhenius equation and the reaction activation energy was 8.65kJ/mol.
