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CO2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CO2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。

Abstract

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 CO2 were investigated. Moreover

the adsorption kinetic characteristics of the adsorbents at different air humidities were studied. The results showed that

the maximum CO2 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.
