  4. 3. CO2 Separation - from Aqueous Amine Solvent to Ionic Liquid-based solvent

    Författare :Nan Wang; Xiaoyan Ji; James Glynn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : CO2 separation is one of the most important roles in CO2 mitigation target as many human production activities (e.g., cement, iron and steel, and biogas productions) cause CO2 emissions. The solvent-based absorption is the most mature technology for CO2 separation, where different solvents capture CO2 either in chemical or physical absorptions. LÄS MER

  5. 4. Cellulose processing in ionic liquid based solvents
