    • Addition of potassium iodide reduces oxidative degradation of monoethanolamine (MEA) 

      Buvik, Vanja; Ramos Wanderley, Ricardo; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)
      We introduce the addition of stable salts to aqueous MEA as a way of inhibiting oxidative degradation reactions. We performed oxidative degradation studies in aqueous MEA containing sodium chloride (NaCl) and potassium ...

    • Analysis and selection of optimal solvent-based technologies for biogas upgrading 

      Carranza Abaid, Andres; Ramos Wanderley, Ricardo; Knuutila, Hanna K; Jakobsen, Jana Poplsteinova (Journal article; Peer reviewed, 2021)
      Biogas upgrading is an important industrial process for producing biomethane, a sustainable energy source with low carbon footprint. There are three main solvent-based alternatives for biogas upgrading: water scrubbing, ...

    • Interfacial Dilational Rheology of Molecular Films in DC Electric Fields 

      Mhatre, Sameer; Simon, Sebastien Charles; Sjøblom, Johan (Journal article; Peer reviewed, 2022)
      We present a novel technique to measure the interfacial dilational rheology of a molecular film adsorbed at a water–oil interface in a direct-current (dc) electric field. A film of a highly polar subfraction of asphaltenes ...

    • A Norwegian steam explosion biorefinery 

      Moe, Størker T.; Hermundsgård, Dag Helge; Tanase-Opedal, Mihaela; Brusletto, Rune (Chapter, 2023)

    • Reversed Hysteresis during CO Oxidation over Pd75Ag25(100) 

      Fernandes, Vasco Rafael P; Van der Bossche, Maxime; Knudsen, Jan; Farstad, Mari Helene; Gustafson, Johan; Venvik, Hilde Johnsen; Grönbeck, Henrik; Borg, Anne (Journal article; Peer reviewed, 2016)
      CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and ...
