  1. 1. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Milda Grikainyte; [2022]
    Keywords : Water-gas shift; catalyst; chemical engineering; Chemistry;

    Abstract : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. READ MORE

  3. 2. Assessment of how environmental variables and vegetation structure influence peatland carbon fluxes

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Bernabé Ramírez; [2021]
    Keywords : ;

    Abstract : Boreal peatlands are important ecosystems from a carbon balance perspective because they are natural carbon sinks as a result of millennia of peat formation. However, due to climate change, these ecosystems are susceptible to changes in hydrology and temperature. READ MORE

  6. 5. GHG reduction by rewetted arable land : a study on cultivated peatland for biogas production in temperate climate in Sweden

    University essay from

    Author : Mireille LMI Martens; [2017]
    Keywords : Phragmites australis; Typha latifolia; methane yield; paludiculture; peatland;

    Abstract : Hydrophytes can be cultivated on rewetted drained peatland and used as substrate to produce biogas which can be utilized as vehicle fuel. This results in less GHG from rewetted peat soils and at the same time leads to renewable energy that substitutes fossil fuels. READ MORE
