摘要

本文根据吸附势理论

预测了CO/CO_2和CO/N_2两种二元混合气在载铜活性炭（C/Cu)上的吸附平衡数据

该数据与实测结果的比较表明

上述理论误差较小

并且适用于CO/CO_2这类共沸体系

从而推广了这一理论的应用范围.相应的比较结果还表明

Flory-Huggins空穴溶液模型和负荷比夫联方程均不能描述CO/CO_2的共沸行为.

Abstract

The equilibrium data or CO-CO2

CO-N2 on active carbon-supported copper were predicted by the potential-theory model proposed by R. T. Yang et al. and tested against experimental data with satisfactory result

especially for CO-CO2 system

which show an azeotropic behavior. The prediction requires only experimental equilibrium data of single gas adsorption on the adsorbent

which are correlated by Dubinin-Astakhov equation. In contrast with the potential theory model

Flory-Huggins vacancy solution theory model and loading ratio correlation equation failed to predict the adsorption of CO-CO2 on active carbon-supported copper

because the adsorption of CO on the adsorbent was attributed to the formation of complex between CO and copper supported on active carbon.
