  1. 1. Modeling competitive adsorption of binary mixtures of volatile organic compounds

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

    Författare :Michelle Janus; [2023]
    Nyckelord :;

    Sammanfattning : Adsorption is a common technique for the removal of volatile organic compounds (VOCs) from industrial waste streams. The multi-component adsorption on zeolites, particularly the interactions between VOCs and water vapor is sparsely understood and is yet to be described by empiric and full-physical models. LÄS MER

  3. 2. Design and processing of metal-organic frameworks for greenhouse gas capture

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Evelina Wiksten; [2023]
    Nyckelord :Metal-organic frameworks; zeolitic imidazolate frameworks; carbon capture; gas adsorption; direct ink writing;

    Sammanfattning : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. LÄS MER

  4. 3. Baggalútar from Hvalfjörður (Iceland): Enigmatic spheroids of hydrothermally altered basaltic tephra

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Emmie Djuse; [2022]
    Nyckelord :Baggalútar; Iceland; basalt; Hvalfjörður; zeolites; volcanic spherulite; spheroids; Baggalútar; Island; basalt; Hvalfjörður; zeoliter; vulkaniska sfäruliter; sfäroider;

    Sammanfattning : Baggalútar are well-rounded spheroids that typically measures 16-18 mm in size and have a brownreddish appearance. They can be found in the Hvalfjörður bay in SW Iceland. LÄS MER

  5. 4. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emma-Helena Ericsson; [2020]
    Nyckelord :AOX; EOX; wastewater treatment plant; column test; granular activated carbon; natural zeolites; Polonite r ; Zugol;

    Sammanfattning : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. LÄS MER

  7. 5. Catalytic Upgrading of Fast Pyrolysis Bio-oil Using Zeolites

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Elena Wikberg; [2019]
    Nyckelord :;

    Sammanfattning : Fast pyrolysis bio-oil is considered as a possible source for production of liquid bio-fuels and bio-chemicals enabling the necessary transition to a renewable energy system. In this Master’s thesis work the upgrading of fast pyrolysis bio-oils with Fluid Catalytic Cracking (FCC) conversion process at industrially relevant conditions is studied using Fluid Catalytic Cracking Micro Activity Test (FCC MAT) unit at RISE ETC in Piteå, Sweden.
