摘　　要：为解决基于固态胺材料的再生式CO_(2)去除技术在便携式生保系统中的应用问题,开展了固态胺材料吸附去除CO_(2)的性能研究。进行了不同吸附温度、入口CO_(2)浓度、气体流量条件下固态胺吸附CO_(2)的穿透试验,获得了相应的穿透曲线;利用Wheeler方程对穿透曲线进行了拟合,得到了相应的拟合方程、平衡吸附量等结果。结果表明:通过Wheeler方程能够准确描述固态胺吸附CO_(2)的行为;获得了CO_(2)穿透率分别为10%和50%时的穿透时间与气体流量间的线性关系方程,方程可应用于预测固态胺反应器性能、切换周期等,使评估反应器性能的试验大为简化。To solve the application problem of regenerative CO_(2) technology based on solid amine in portable life support systems,a performance study on solid amine in CO_(2) removal was carried out.The breakthrough tests of solid amine adsorbing CO_(2) at different adsorption temperature,inlet CO_(2) concentrations and gas flow rates were carried out,and the corresponding breakthrough curves were obtained.The Wheeler equation was used to fit the breakthrough curve,the corresponding fitting e-quation and results such as the equilibrium adsorption capacity were obtained.The results showed that the Wheeler equation could accurately describe the behavior of solid amine adsorbing CO_(2),the linear relationship equation between breakthrough time and gas flow rate were obtained when the CO_(2) breakthrough rates were 10%and 50%,respectively.The equation can be applied to predict the performance of solid amine reactor,switching period,etc.,which will greatly simplify the testing of reactor performance evaluation.
