摘　　要：本文从6组不同种类的固态胺的吸脱附动力学入手,测出3种温度下的6组胺吸、脱附CO2时的质量变化数据,通过Avrami动力学模型拟合得到不同温度下吸、脱附的动力学常数k.本文发现N,N'-二乙基乙二胺作为一种乙基仲胺,其吸、脱附动力学常数k比其他胺高,是一种吸、脱附性能都比较好的胺,这种类型的胺更适合在密闭空间中作为高效的固态胺吸附剂使用.Based on the adsorption and desorption kinetics of 6 groups of different kinds of solid amines,the mass variation data when absorbing and desorbing C02 by 6 groups of amines at 3 temperatures,and the kinetic constant k of adsorption and desorption at different temperatures are obtained through Avrami kinetic model fitting.lt is found that N,N'-Diethylethylenediamine,as an ethyl secondary amine,has higher adsorption and desorption kinetic constants k than other amines,and is an amine with better adsorption and desorption performance.This type of amine is more suitable to be used as an efficient solid amine adsorbent in a confined space.
