  1. 1. Characterization of NiMo catalysts with noble metal promoters

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  3. 2. Impact of Peroxide Speciation on the Kinetics of Oxidative Dissolution of UO2

    University essay from KTH/Kemi

    Author : Hazal Aydogan; [2022]

    Abstract : Slutförvaring av använt kärnbränsle måste vara säker under 100 000 år eller mer för att förhindra att miljön skadas och att människor påverkas av långlivade radionuklider. Även om anläggningar för geologiskt djupförvar är utformade för att vara hållbara i många år, kan använt kärnbränsle komma i kontakt med grundvattnet i händelse av att flera barriärer brister.

  5. 4. Method development for quality control of the primary explosive, Potassium 4,6-Dinitrobenzofuroxan (KDNBF)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Edvin Elmroth; [2020]
    Keywords : “Green” explosives; KDNBF; GC-FID; HPLC-UV VIS; Potentiometric titration;

    Abstract : “Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. READ MORE

  6. 5. Solvents and solvent blends for the polymers TQ1 and N2200.
