    • Supported Manganese Oxide Catalysts for NO Oxidation in Nitric Acid Production 

      Østrådt, Beate Meisland (Master thesis, 2018)
      Nitric acid is an important bulk chemical in the petrochemical industry, and the main product is ammonium nitrate for fertilizers. It is produced by the Ostwald process, where one of three chemical steps is the oxidation ...

    • Synthesis and applications of carbon nanomaterials: from quanta dots to microspheres 

      Skodvin, Daniel (Master thesis, 2017)
      In this work, activated carbon fibers and activated carbon spheres were pre- pared through physical activation with CO2 and steam. The precursors used were polyaniline (PANI) and resorcinol-formaldehyde polymer spheres (RF ...

    • Synthesis and characterisation of tungsten carbide 

      Rui, Haakon Marius Vatten (Master thesis, 2015)
      The supply of tungsten carbide is very limited, which has resulted in EU categorizing tungsten as a critical raw material. Instead of substituting tungsten entirely, this paper has looked into the possibility of using SiC ...

    • Synthesis of high-temperature solid sorbents for CO2 capture 

      Lilleng, Ane Sofie (Master thesis, 2018)
      The use of fossil fuels have escalated since the first industrial applications at the mid 19th century with a consequence of increased emissions of carbon dioxide and other green house gases. As a result, the global climate ...

    • Synthesis of Tungsten Carbide 

      Langfjæran, Sebastian (Master thesis, 2017)
      Tungsten is a rare element and the supply is limited. It has some unique properties, such as very high density, very high melting point, high electrical conductivity, high tensile strength and hardness, and it is a part ...

    • The Effect of Potassium on Cobalt-based Fischer-Tropsch Catalysts of Small and Medium Cobalt Particle Sizes 

      Save, Jonas (Master thesis, 2018)
      The effect of potassium on a 20 wt.% Co - 0.5 wt.% Re/-Al2O3 catalyst consisting of small and medium cobalt particle sizes were investigated. The particle sizes were adjusted by using different mixtures of ethylene glycol ...

    • Tuning of perovskite composition for NO oxidation 

      Hyrve, Signe Marit (Master thesis, 2018)
      Nitric acid (HNO3) is an important building block in the chemical industry, and special for production of fertilizers. It is manufactured by the Ostwald process, where oxidizing NO to NO2 is one of the three chemical steps. ...
