  1. 21. High Temperature Corrosion in Gasification of Biomass and Waste The effect of H2 and H2O

    Författare :Hamed Hoseini Hooshyar; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Gasification of biomass and waste is a key issue in reducing the usage of fossil fuels especially in the transportation section (i.e. fuels for vehicles) and thus enabling a more sustainable society. The chemical composition of the produced gas dictates the boundaries within which e. LÄS MER

  4. 23. 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

  5. 24. Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate

    Författare :Mauritz Johan Ryding; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clusters; ions; water; ammonia; pyridine; bisulphate; cross sections; collision induced dissociation CID ; kinetic modelling; electrospray ionization ESI ; time-of-flight TOF ; mass spectrometry;

    Sammanfattning : Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. LÄS MER

  7. 25. Structure, Bonding and Chemistry of Water and Hydroxyl on Transition Metal Surfaces

    Författare :Klas Andersson; Anders Nilsson; Falko Netzer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-level spectroscopy; surface chemistry; water; hydroxyl; metal surfaces; adsorption; structure; hydrogen bonding; Chemical physics; Kemisk fysik;

    Sammanfattning : The structure, bonding and chemistry of water and hydroxyl on metal surfaces are presented. Synchrotron based x-ray photoelectron- and x-ray absorption spectroscopy along with density functional theory calculations mainly form the basis of the results. LÄS MER
