    Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

    Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER

  3. 2. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Författare :Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. LÄS MER

  4. 3. On thermodynamic properties of aqueous ethylamine mixtures and modelling of excess properties

    Författare :Åsa Ulrika Burman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Ethylenediamine (EDA) is a bifunctional amine used for several different purposes such as for production of the Ethylenediaminetetracetric acid (EDTA) that is used as a chelating agent in detergents but also for fungicides, bleaching activators etc. In many applications very high purity is needed and the removal of the byproduct Ethylethylenediamine (EtEDA) has proven to be difficult.

  5. 4. Thermodynamic modelling of carbides in multicomponent systems : theoretical and experimental approach

    Författare :Andreas Markström; Bo Sundman; José Garcia; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis concerns thermodynamic modeling of carbides in multicomponent systems. Focus has been made on systems interesting for cemented carbide production but the results are also useful for many other application were the material consist of different carbides, for example tool steels/high speed steels.
