Abstract

The features of cyclic adsorption processes are considered and the fact of necessity to predict a decrease in the dynamic activity of adsorbents during their operation is exhibited. By analogy with recycling chemical processes, phenomenological concepts of the general pattern of sorbent deactivation were developed, which made it possible to form mathematical models of trivial and prolonged deactivation in cyclic and continuous adsorption processes. Simple approximate equations are derived that sllow predicting the change in the dynamic activity of the adsorbent under conditions of long-term operation on the basis of short-term laboratory studies. Examples of the results of predicting the operation of various adsorbents during the purification of gas and liquid phase streams are presented. The developed mathematical models provide acceptable convergence of the calculation results with experimental data.

吸附剂操作活性的数学模型

摘要

考虑了循环吸附过程的特征，并显示了必须预测吸附剂在其运行过程中动态活性降低的事实。通过类似于循环化学过程，开发了吸附剂失活一般模式的现象学概念，这使得在循环和连续吸附过程中形成微不足道和长期失活的数学模型成为可能。根据短期实验室研究，推导了简单的近似方程，该方程缓慢预测了长期运行条件下吸附剂的动态活性变化。给出了在气相和液相流的净化过程中预测各种吸附剂运行情况的结果示例。
