摘　　要：膜法分离CO2一直被认为是最具有发展前景的CO2分离方法之一.文章介绍了膜法分离CO2两种主要机理,列举了传统分离CO2的有机膜材料及新型复合膜材料,同时,分析了在燃煤湿法脱硫净烟气膜法分离CO2中烟气共存气态组分和细颗粒物对于膜分离CO2产生的影响.最后,展望了在燃煤脱硫净烟气中膜法分离CO2的发展前景.Membrane separation of CO2 continued to be considered as one of the methods of most prospect.This paper gives a description of two main mechanisms of it,enumerating conventional organic membrane materials for CO2 separation,as well as some new composite membrane materials.Meanwhile,the effects of the coexistence gaseous component and fine particles in coal-fired flue gas after wet desulphurization on the membrane separation of CO2 are analysed.At last,it gives a simple development prospect of membrane separation of CO2.
