  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. Effect of powder spray drying on catalyst formulation in tablet form

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kajsa Wahlgren; [2023]
    Nyckelord :Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    Sammanfattning : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. LÄS MER

  4. 3. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Wiktorsson; [2022]
    Nyckelord :VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

  5. 4. Ethylene to Liquid Hydrocarbons by Heterogeneously Catalyzed Oligomerization on ZSM-5

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikalisk kemi

    Författare :Gustav Halldén; [2022]
    Nyckelord :ethylene; ethane; oligomerization; catalyst; heterogeneous catalysis ZSM-5; zeolite;

    Sammanfattning : The aim is to produce aliphatic liquid hydrocarbons using heterogeneous ethylene oligomerization. Thiscould potentially produce renewable synthetic fuels. Heterogeneous catalysis has some advantages overhomogeneous catalysis regarding some sustainability aspects. LÄS MER

  7. 5. Biobased carbon aerogels incorporated with zeolite nanoplates for carbon dioxide adsorption

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Maria Harila; [2021]
    Nyckelord :biobased; carbon aerogel; lignin; cellulose nanofiber; adsorption; carbon dioxide; zeolite nanoplate;

    Sammanfattning : Over the last 100 years there has been an increase of greenhouse gases (CO2, CH4 and N2O) in the atmosphere. These gases cause several problems with the climate on Earth, such as increasing problems with extreme weather. One way to decrease the outlet of carbon dioxide is by adsorption and capture of CO2.
