摘要：

A kind of new fixed carrier membrane material for CO2 separation, N-vinyl-γ-sodium aminobutyrate-sodium acrylate copolymer (VSA-SA), was synthesized by radical copolymerization and hydrolysis. The composite membrane was developed with VSA-SA as an active layer and polysulfone (PS) ultra-filtration membrane as the support. Several kinds of metal ion cross-linkers were used to improve the performance of the composite membrane. The effects of cross-linking time on the cross-linked membrane were also studied. The membrane performance was investigated by using feed gases with different ratios of CO2 to CH4. The results showed that the composite membrane was more suitable for the separation and removal of the natural gas with high CH4 content. The prepared membrane was stable during one week testing.
