  1. 1. 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

  3. 2. Study of Reverse Water Gas Shift reaction using bimetallic catalysts on active supports : The case of unpromoted and K-promoted FeCu/CeO2

    Master-uppsats, KTH/Kemiteknik

    Författare :Carlo Sala; [2022]
    Nyckelord :CO2 utilization; RWGS; catalyst; active catalytic support; characterization; CO2 användning; RWGS; katalysator; aktiva katalysatorbärare; karakterisering;

    Sammanfattning : Reverse Water Gas Shift Reaction (RWGS) är en attraktiv lösning för CO2-använding och minskning av utsläppen i atmosfären. Denna reaktion begränsas av termodynamiken och det finns problem med storskalig tillämpning. För att förbättra genomförandet av processen krävs utveckling av en effektiv katalysator. LÄS MER

  4. 3. Investigation into the Removal of the By-product NDMA (N-Nitrosodimethylamine) from Ozonation Process in Wastewater Treatment

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Zehao Li; [2021]
    Nyckelord :Water resources engineering; Ozonation; NDMA; Wastewater; pharmaceutical; Diclofenac; Ibuprofen; Naproxen; Technology and Engineering;

    Sammanfattning : In people’s modern life, daily usage of artificial compounds such as active pharmaceuticals ingredients (API) is usual. These compounds are likely to end up as micropollutants in the municipal wastewater. Municipal wastewater is the major source of pharmaceuticals in the aquatic environment. LÄS MER

  5. 4. Möjligheten att minska metallhalten i lakvatten med sulfatreducerande bakterier

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Sofie Sunesson; [2020]
    Nyckelord :Metals; Landfill; Leachate; SRB; Precipitation; Sulfide; Applied microbiology; Teknisk mikrobiologi; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Anaerobic treatment of landfill leachate using sulphide precipitation was tested at pilot scale for the purpose of heavy metal removal. The emission of leachate is heavily regulated by Swedish authority and the overall concentrations of heavy metals is expected to rise as landfills contain less organic matter. LÄS MER

  7. 5. Groundwater denitrification by fluidized bioelectrochemical systems

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lena Bonin; [2020]
    Nyckelord :Bioelectrochemistry; fluidized bed reactor; bioremediation; denitrification; groundwater; reduced graphene oxide;

    Sammanfattning : Groundwater (GW) accounting for most of the freshwater available around the World, finding sustainable techniques to depollute it is of crucial importance for safe drinking water supply. The extensive use of fertilizers in the agriculture, as well as other anthropogenic activities, are contributing to the excessive nitrate levels in some aquifers. LÄS MER
