对传统的化学吸附动力学模型不能够反映络合物分子之间化学反应动力学这一问题,文中对不同的络合物分子间距的CaCl_2-NH_3的吸附与解吸过程进行了研究,结果表明,络合物分子之间的化学反应动力学对吸附过程影响较大。通过增加能够反映络合物分子反应动力学以及络合物分子间传质过程的项,对传统的化学吸附动力学模型进行了改进,试验表明,改进的化学吸附动力学模型能够很好地反映试验现象。对解吸过程的研究则表明,解吸过程主要受络合物分子内部反应动力学的影响,络合物分子之间的反应动力学对解吸过程的影响不大。
In order to solve the problem of that the traditional chemical adsorption kinetic models can t simulate the chemical reaction kinetics of complex compounds precisely,the adsorption and desorption processes of CaCl_2-NH_3 with different distances between complex molecules are researched. The results show that the chemical reaction dynamics between complex molecules is very important for adsorption process.After the items for reaction dynamics and for mass transfer performances between complex molecules are a...
