1. 1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

   Master-uppsats, KTH/Fysik

   Författare :Serena Ambrosino; [2024]
   Nyckelord :Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

   Sammanfattning : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. LÄS MER

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

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

   Sammanfattning : 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. LÄS MER

4. 3. Integrating biomass gasification with electric arc furnace steel making

   Master-uppsats, KTH/Energiprocesser

   Författare :Filippa Andersson; [2023]
   Nyckelord :Electric arc furnace; EAF off-gas; gasification; CCU; process integration; Ljusbågsugn avgasrök; ljusbågsugn; förgasning; kolavskiljning; process integration;

   Sammanfattning : Utsläppen av växthusgaser ökar över hela världen och nya tekniker används för att minska utsläppen. 7% av utsläppen kommer från stålsektorn. 25% av världens stålproduktion görs via återvinningstekniken ljusbågsugn. Genom återvinningsprocessen släpps det ut 500kg CO2 per ton producerat flytande stål. LÄS MER

5. 4. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Alma Fahlén Hammar; [2023]
   Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

   Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

7. 5. Hydrogen as an energy carrier : A literature study on mass transportation

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Efthymios Revenas; [2023]
   Nyckelord :hydrogen; production; storage; transportation; regulations; policies;

   Sammanfattning : In the current Master's Thesis, the use of hydrogen as a fuel in transportation, the state of hydrogen in the European Union as well as the rest of the European countries' future for adopting hydrogen in the mass transportation sector, were researched. Initially, the thesis provides an overview of hydrogen classification, production methods, storage methods, and transportation methods. LÄS MER
