1. 1. 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

3. 2. Vidareutveckling av katalysatorer för pre-reforming i bränslecellssystem

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Alexander Schönauer; [2020]
   Nyckelord :catalysis; pre-reforming; fuel cells; SOFC; DMSOFC; heterogeneous catalysts; propane reforming; chemical engineering; kemiteknik; Technology and Engineering;

   Sammanfattning : Heterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. LÄS MER

4. 3. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :FAISAL SEDEQI; [2020]
   Nyckelord :;

   Sammanfattning : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. LÄS MER

5. 4. Improved interconnect materials for next-generation Solid Oxide Fuel Cells

   Master-uppsats, KTH/Materialvetenskap

   Författare :Pablo Collantes; [2019]
   Nyckelord :Solid Oxide Fuel Cells; High Temperature Corrosion; Self-healing; Interconnects;

   Sammanfattning : Solid Oxide Fuel Cells (SOFC) are attractive candidates in the search for cleaner and energy efficient production due to their numerous advantages such as fuel flexibility, modularity and exceptional efficiencies when combined heat and power is harnessed. A key element in its design are the interconnects which are mainly manufactured from custom ferritic stainless steels to carry the electricity between two adjacent cells. LÄS MER
