  1. 16. Detaljkonstruktion av tvättmaskin för anodpåsar

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

    Författare :Hasan Hasan; [2019]
    Nyckelord :Anodpåse; ädelmetaller;

    Sammanfattning : The silver refining process is a extracting of pure silver which happen in large tanks filled with silver nitrate electrolyte solution. In each tank there are 6 Doré anodes, where they are placed in anode bag. LÄS MER

  3. 17. Monolithic Pt & Pd catalyst - Method for development of Pt & Pd monolithic catalyst in FORMOX™ ECS unit

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emil Gammelgaard; [2018]
    Nyckelord :Heterogenous Catalysis; Emmision control system; Platinum; Palladium; Monolith; Chemical engineering; Kemiteknik; Technology and Engineering;

    Sammanfattning : FORMOX™ is a formaldehyde production process, utilizing a metal oxide catalysts. The new generation of plants is pressurized, therefore the turbo charger concept has been developed. LÄS MER

  4. 18. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Sebastian Pfaff; [2017]
    Nyckelord :plif; laser diagnostics; catalysis; carbon monoxide; carbon dioxide; palladium; planar laser induced fluorescence; Physics and Astronomy;

    Sammanfattning : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. LÄS MER

  5. 19. Oligomerization of ethylene and ethanol into fuel through heterogenous catalysis

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mergim Pacolli; Marko Ristovic; [2017]
    Nyckelord :chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The goal and ambition of this thesis has been to investigate a topic that could lead to a possible solution to the environmental crisis we are witnesses of. Replacement of fossil fuels is an essential step towards a renewable society that needs to be taken. LÄS MER

  7. 20. 2-Hydroxypyridine-Ligated Pd-complexes as pre-catalysts in Hydrogen Borrowing Chemistry α -Alkylation of Ketones Using Alcohols

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ayesha Kanwal; [2017]
    Nyckelord :Hydrogen Borrowing in activation of alcohols; Palladium in Catalysis; hydrogenation and dehydrogenation reactions; hydrogen borrowing concept for hydrogenation and dehydrogenation reactions; 2-hydroxyquinoline Ligand; 2-hydroxy pyridine ligands; inorganic chemistry; oorganisk kemi; Chemistry;

    Sammanfattning : An efficient method for selective alpha-alkylation of ketones with alcohols was developed using 2-hydroxypyridine-based ligands coordinated by palladium as pre-catalysts. The reactions were performed without additional additives under mild reaction conditions. The method is environmentally friendly to build C-C bond as water is the only byproduct. LÄS MER
