  1. 1. Study of Catalyst Deactivation in Three Different Industrial Processes

    Författare :Ann-Charlotte Larsson; Mehri Sanati; Ferruccio Trifiro; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deactivation; catalyst; SCR; VOC; steam reforming; aerosol particle; potassium; zinc; ash salts; biomass; organosilicon; Chemical engineering; Kemiteknik; Kemi; Chemistry;

    Sammanfattning : Deactivation of catalysts were investigated focusing on three industrial processes: 1) Selective Catalytic Reduction (SCR) for abatement of NOx from biomass combustion using V2O5-WO3 /TiO2 catalysts; 2) Catalytic oxidation of volatile organic compounds (VOC) from printing industries using a Pt/γ-Al2O3 catalyst; and 3) Ni and Pt/Rh catalysts used in steam reforming reaction of bio-syngas obtained from biomass gasification.The aim has been to simulate industrial conditions in laboratory experiments in order to comprehend influence of compounds affecting catalysts performance.

  3. 2. Reducing ships' fuel consumption and emissions by learning from data

    Författare :Fredrik Ahlgren; Marcus Thern; Maria E. Mondejar; Cecilia Österman; Ann-Charlotte Larsson; Erik Dahlquist; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shipping; energy efficiency; orc; machine learning; emissions; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. LÄS MER
