      Lei, Linfeng; Bai, Lu; Lindbråthen, Arne; Pan, Fengjiao; Zhang, Xiangping; He, Xuezhong (Peer reviewed; Journal article, 2020)
      CO2 removal from gas streams using energy-efficient and environmentally friendly separation technologies can contribute to achieving a low-carbon energy future. Carbon membrane systems for hydrogen purification, post-combustion ...
    • Poly(vinylimidazole-co-butyl acrylate) membranes for CO2 separation 

      Ting, Song; Deng, Jing; Deng, Liyuan; Bai, Lu; Zhang, Xiangping; Zhang, Suojiang; Szabo, Peter; Daugaard, Anders E. (Peer reviewed; Journal article, 2019)
      Room temperature ionic liquids (RTILs) are known to exhibit high CO2 solubility, which makes them interesting candidates for separation and purification of mixed gas streams. Particularly, RTILs based on imidazoles have ...
