摘　　要：采用多种MEA无水溶剂(MEA+苯甲醇、MEA+二甘醇、MEA+N-甲基吡咯烷酮)进行CO2的吸收研究,通过与MEA水溶剂比较研究无水溶剂的性能以及工业应用潜力。实验结果表明:采用溶剂(苯甲醇、二甘醇、N-甲基吡咯烷酮)代替水,其吸收能力与解吸能力均有所降低,但其解吸速率大大增加,解吸能耗降低;通过3次循环实验,得出无水溶剂的稳定性较好,有一定的工业应用前景。Three kinds of non-aqueous MEA solutions （MEA ＋ benzyl alcohol,MEA ＋ diethylene glycol,MEA ＋ 1-methyl-2-pyrrolidinone） are used to study the absorption of CO2.Compared with the aqueous MEA solution,the properties of non-aqueous solutions and their potential industrial applications are also investigated.The results show that,by using non-aqueous solvents （benzyl alcohol,diethylene glycol,1-methyl-2-pyrrolidinone） instead of water,the absorption and desorption capacity decrease.However,the rate of desorption increases greatly and the energy consumption of desorption is reduced.After ternary cycle experiments,non-aqueous solutions show good stability and have a great potential for industrial application.
