| 摘 要： | 通过对不同气-固体系的考察,提出了一种以线性升温吸附-非线性降温吸附-线性升温脱附为主要实验步骤的程序控温吸-脱附方法。同时解决了吸、脱附动力学的计算问题。对实际体系的研究结果表明:借助这一动态分析手段,可在一次实验中观察到吸、脱附的全部动态过程,方便地进行活化吸附和非活化吸附的研究,并可计算得到有关的吸、脱附动力学参数,为进行吸、脱附的理论探讨与实际应用提供了一种有效的实验方法。

| Abstract: | After studying some different gas-solid systems a dynamic analysis method is proposed which consists of three mainsteps: adsorption controlled by a linearly increasing temperature program; adsorption controlled by a non linearly de creasing temperature program and dcsorption under a linearly increasing temperature. The calculation about the activation energies of adsorption and desorption and the heat of adsorption is put in practice. The results of studies for some gas-solid systems show that the complete dynamic procedure of adsorption and desorption can be observed and active adsorption and inactive adsorption can be conveniently studied by this dynamic analysis method. |
