为解决基于固态胺材料的再生式CO2 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CO2 的性能研究.进行了不同吸附温度、入口CO2 浓度、气体流量条件下固态胺吸附CO2 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CO2 的行为;获得了CO2 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.
Behavior Research of Solid Amine in CO2 Removal
To solve the application problem of regenerative CO2 technology based on solid amine in portable life support systems,a performance study on solid amine in CO2 removal was carried out.The breakthrough tests of solid amine adsorbing CO2 at different adsorption temperature,inlet CO2 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 CO2,the linear relationship equation between breakthrough time and gas flow rate were obtained when the CO2 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.
