摘要
基于原位合成工艺制备了一种树脂基固态胺吸附剂,并探究了相对空气湿度(30%~90%)、吸附温度(30~90℃)和吸附时间等因素对吸附剂CO_(2)吸附性能的影响,同时研究了不同空气湿度下吸附剂的吸附动力学特性。研究表明:树脂基固态胺吸附剂在空气中的最大CO_(2)吸附容量达到2.38 mmol/g,空气湿度和吸附温度对吸附速率具有显著影响,当空气湿度高于50%,吸附温度处于25~50℃时具有最佳的吸附效率;该吸附剂表现出很好的吸脱附循环稳定性,这归因于其出色的耐高温特性。
A resin-based solid amine adsorbent was prepared based on in-situ synthesis technology.The effects of air humidity(30%~90%),adsorption temperature(30~90℃)and adsorption time on the adsorption performance of CO_(2) were investigated.Moreover,the adsorption kinetic characteristics of the adsorbents at different air humidities were studied.The results showed that,the maximum CO_(2) adsorption capacity of the resin-based solid amine adsorbents in the air reached 2.38 mmol/g,and the air humidity and adsorption temperature had significant effects on the adsorption rate.The optimal adsorption efficiency was obtained when the air humidity was higher than 50%and the adsorption temperature was 25~50℃.The adsorbent exhibits very good cycle stability due to its excellent high temperature resistance.
