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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  3. 2. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elias Önerud; [2023]
    Keywords : Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Abstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

    Abstract : The biodiesel sector has witnessed tremendous growth in recent years, leading to a significant increase in glycerol production as a by-product. Addressing the challenge of glycerol valorization is crucial for the sustainability of the biodiesel industry. READ MORE

  5. 4. Impact of pre-treatments on the brightness stability of a conventional and near neutral pH ECF-light bleaching sequence

    University essay from KTH/Fiber- och polymerteknologi

    Author : Ali Amirjani; [2023]
    Keywords : ECF; Bleaching; Pulp; AOX; Brightness Stability; ECF; Blekning; Massa; AOX; Ljushetsstabilitet;

    Abstract : Syftet med denna studie är att undersöka inverkan av förbehandlingar på ljushetsstabiliteten av Northern Bleached Softwood Kraft (NBSK) som har blekts enligt (OO) (OP) D/Dn (PO) bleksekvensen. Effekten av förbehandling med xylanas (X), mild sur (A), DTPA (Q) samt ett kombinerad DTPA- & xylanassteg (Q+X) har studerats. READ MORE

  6. 5. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lina Näslund; Gabriella Petersson; [2023]
    Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE
