  1. 1. Redox Materials in Hydrogen Production : Investigation of state-of-the-art redox materials in thermochemical cycles for hydrogen production via solar energy

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Saga Berneryd; [2023]
    Nyckelord :;

    Sammanfattning : This bachelor thesis work has investigated different redox materials in 2-step thermochemical water splitting processes for solar-driven hydrogen production. Materials have been mapped out by their results from experimental activity and by the conditions the tests were conducted in. LÄS MER

    Sammanfattning : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  4. 3. A simulation model of a reactor for ethylene oxide production

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Hanna Perzon; [2015]
    Nyckelord :kemiteknik; chemical engineering; Chemistry;

    Sammanfattning : This thesis has been performed in the ethylene oxide plant at Akzo Nobel in Stenungsund. Ethylene oxide is an important ethylene based intermediary compound. The primary use for ethylene oxide is in the manufacture of derivatives such as ethylene glycol, surfactants and ethanolamine’s. LÄS MER
