  1. 1. Synthesis and Characterization of NCN Pincer Nickel Complexes

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Joel Klarén; [2023]
    Nyckelord :Pincer complexes; Nickel; organometallic chemistry; synthesis; NCN Pincer Nickel Complexes; organic chemistry; Chemistry;

    Sammanfattning : In this work, a series of nickel NCN complexes and ligands have been synthesized with the goal of determining whether they can perform so-called CO2-insertion reactions into Ni-C bonds. So far, only the synthesis of the Ni-Br precursor complexes to the previously mentioned Ni-C complexes have been synthesized. LÄS MER

  3. 2. Characterization of NiMo catalysts with noble metal promoters

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filip Hallböök; [2023]
    Nyckelord :Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

    Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER

  4. 3. Optimal Portfolio Allocation of Commodities for the Swedish Investor

    Kandidat-uppsats,

    Författare :Sebastian Henfalk; Alexandra Wesley; [2021-08-17]
    Nyckelord :Optimal Portfolio Allocation into Commodities; OMXS30GI; Bloomberg Commodity Index BCOM ; Sub-Sectors; Sharpe Ratio; Swedish Investor; Financialization; Diversification; Hedge; Precious Metals; Inflation; Råvaror; Optimal Allokering; Ädelmetaller;

    Sammanfattning : Commodities have historically been seen as great diversifiers to stocks and bonds. Following the financialization in late 1990s and early 2000s this began to be questioned by previous research due to increasing correlations with the stock market, which has created a need for further research with in the field.

  5. 4. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Per Kautto; [2020]
    Nyckelord :palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Sammanfattning : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. LÄS MER

  7. 5. 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
