  1. 1. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Melker Axelsson; [2023]
    Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

  3. 2. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

  4. 3. Pilot scale partial denitratation coupled anammox: an evaluation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Tobias Ellingsen; [2022]
    Keywords : mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Abstract : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. READ MORE

  5. 4. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    University essay from KTH/Hälsoinformatik och logistik

    Author : Mikael Granberg; [2022]
    Keywords : PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Abstract : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

  6. 5. Temporal and spatial trends of heavy metal leakage from acid sulfate soils : Leakage of Ni, Zn, Cu and Fe to freshwater and marine sediments, North-eastern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Bella Blomkvist; [2020]
    Keywords : acid sulfate soils; leaching; Persöfjärden; sulfide oxidation; metal pollution;

    Abstract : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.
