  1. 21. The role of absorption cooling for reaching sustainable energy systems

    Författare :Susanne Lindmark; Viktoria Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Absorption cooling; trigeneration; district cooling; humidified gas engine; waste heat; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : The energy consumption is continuous to increase around the world and with that follows the demand for sustainable solutions for future energy systems. With growing energy consumption from fossil based fuels the threat of global warming through release of CO2 to the atmosphere increases. LÄS MER

  3. 22. Oxidative Dissolution of Spent Fuel and Release of Nuclides from a Copper/Iron Canister : Model Developments and Applications

    Författare :Longcheng Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model; oxidative dissolution; spent fuel; radiolysis; release; mass transport; radionuclide; hydrogen; corrosion; canister; near field; repository; Chemical engineering; Kemiteknik;

    Sammanfattning : Three models have been developed and applied in the performance assessment of a final repository. They are based on accepted theories and experimental results for known and possible mechanisms that may dominate in the oxidative dissolution of spent fuel and the release of nuclides from a canister.

  4. 23. Diffusive properties of granitic rock as measured by in-situ electrical methods

    Författare :Martin Löfgren; Ivers Neretnieks; Peter Vilks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Diffusion into the rock matrix has been identified as one of the most important retention mechanisms for dissolved contaminants in fractured crystalline rock. In this thesis the diffusive properties of granitic rock, described by the formation factor, have been investigated by electrical methods. LÄS MER

  5. 24. Development of Fischer-Tropsch catalysis for gasified biomass

    Författare :Sara Lögdberg; Sven Järås; Viktoria Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Sammanfattning : In order to secure the energy supply to an increasing population and at the same time limit the damage to Earth, i.e. avoiding a fatal climate change as a result of anthropogenic emissions of greenhouse gases (primarily CO2), immediate action is necessary. LÄS MER

  7. 25. Nanoscientific investigations of electrode materials for supercapacitors

    Författare :Helena Malmberg; Pehr Björnbom; Anders Lundblad; Signe Kjelstrup; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supercapacitor; double layer; microelectrode; ionic transport; Chemical engineering; Kemiteknik;

    Sammanfattning : This doctoral thesis gives background to the field of electrochemical energy storage in supercapacitors. It attempts to place the supercapacitor device in context of available and future technologies for alternative energy systems for transportation. LÄS MER
