  1. 26. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

    Författare :Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

    Sammanfattning : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. LÄS MER

  3. 27. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas

    Författare :Viktor Stenberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; Steam reforming; CCS; Hydrogen; fluidized bed heat exchanger; Oxygen carrier aided combustion; chemical-looping combustion;

    Sammanfattning : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. LÄS MER
