摘要
Abstract
Supported ionic liquid membrane (SILM) has relatively low stability at high cross-membrane pressure difference (0.25-0.3MPa). Polymerized ionic liquid membrane and ionic liquid − polymer mixed membrane can eliminate the instability problem of the SILM. This review presented a summary on the latest developments in the research of SILM,polymerized ionic liquid membrane and ionic liquid − polymer mixed membrane used for CO2 separation with respect to the separation performance,transport mechanism and stability. The research on a three-component mixed-matrix membrane,inorganic particle−ionic liquid−polymer mixed membrane,by dispersing inorganic nano-particles in polymer matrix containing ionic liquid was also introduced. It was indicated that the challenges for the ionic liquid membranes technologies applied on an industrial scale include the trade-off between high CO2 permeation rate and high stability,and the difficulties with the structural arrangement of the mixed membrane. Significant improvements of the separation performance and stability of the ionic liquid membranes can be achieved by developing new membrane materials,improving membrane fabrication techniques to reduce membrane thickness and optimize membrane structure. Inorganic particle − ionic liquid − polymer mixed membrane showed a good prospect in CO2 separation for its higher separation performance combining with better stability. The study on the fabrication,structure,separation performance and mechanism of the new type of membrane will inevitably draw considerable attention.关键词
