  1. 1. CO2 Separation with Ionic Liquids -Property, Gas solubility and Energy consumption

    University dissertation from Luleå tekniska universitet

    Author : Yujiao Xie; Luleå tekniska universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Ionic liquids (ILs) have shown great potential to be used as liquid absorbents for CO2 capture because of its advantages, such as non-volatility, functionality, high CO2 solubility and lower energy requirements for regeneration. A significant amount of research has been carried out, but most of them are on the synthesis of novel ILs and the measurements of CO2 solubility in ILs. READ MORE

  2. 2. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    University dissertation from KTH Royal Institute of Technology

    Author : Nanta Sophonrat; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energiteknik; Energy Technology;

    Abstract : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. READ MORE

  3. 3. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Hanbing He; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layer formation; bed particle; woody biomass; quartz; K-feldspar; olivine; bed agglomeration; deposition; fluidized bed; combustion; gasification; Energiteknik; Energy Engineering;

    Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

  4. 4. On integrity assessment of IGBT-based power stacks used in magnet power supplies for particle accelerators

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Panagiotis Asimakopoulos; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis analyses an electrical testing method for assessing the integrity of an IGBT-based power stack assembly during factory acceptance tests and service stops. The method combines vce measurements with high current in the Zero Temperature Coefficient (ZTC) operating region and with low sensing current within a specific current cycle using a proposed sampling and filtering technique.

  5. 5. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lianpeng Tong; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ruthenium complex; Homogeneous catalysis; Water oxidation; O2 evolution; anionic ligand; Molecular catalyst; Electrocatalysis; Kinetics; Artificial photosynthesis; Light-driven; Immobilization of catalyst;

    Abstract : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. READ MORE
