  1. 6. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE

  3. 7. An annual evaluation of CH4 oxidation in a freshwater lake

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Eldina Cehic; [2020]
    Keywords : Methane oxidation; isotopic fractionation; stratification; open steady-state and closed system.; Metanoxidation; isotopfraktionering; stratifiering; öppet stabilt system och stängt system;

    Abstract : Freshwater lakes constrain its methane (CH4) emissions through CH4 oxidation. CH4 includes three carbon (C) isotopes; the stable isotopes 12C,13C and the unstable and more uncommon isotope 14C. Methanotrophs (i.e. READ MORE

  4. 8. Investigating the methane producing pathway in lab-scale biogas reactors subjected to sequential increase of ammonium and daily acetate-pulsing

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Sofia Moberg; [2020]
    Keywords : Syntrophic acetate oxidation; syntrophic acetate oxidizing bacteria; Wood-Ljungdahl pathway;

    Abstract : Syntrophic acetate oxidizing bacteria convert acetate into hydrogen and carbon dioxide and through the mutualistic syntrophic partnership with methanogens the products are further converted to methane in biogas processes operating at high ammonia concentrations. There is very little known about SAOBs, only five have been characterized and had their genome analyzed. READ MORE

  5. 9. Experimental testing of adsorbents for H2S removal in industrial applications : A comparative study on lifetime and cost effectiveness of different materials

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Fanny Boström; [2019]
    Keywords : ;

    Abstract : Harmful emissions are a global issue and cause trouble for human health and for the environment. There is a wide variety of pollutants and one pollutant is hydrogen sulfide, H2S, that is a member of the group Volatile Sulfur Compounds. READ MORE

  6. 10. Naturbeteskött : ur aspekterna miljö, klimat och näringskvalitet

    University essay from SLU/Department of Molecular Sciences

    Author : Emma Larsson; [2019]
    Keywords : nötkött; naturbete; miljö; klimat; fettsyror; antioxidanter;

    Abstract : Hur livsmedelsförsörjningen ska lösas för en växande befolkning samtidigt som växthusgasutsläppen hålls nere är frågor som står högt upp både på den globala och lokala agendan. Nötkött kommer generellt sett inte väl ut med avseende på växthusgasutsläppen från produktionen. READ MORE
