  1. 16. A Comparative Study of Electrodes and Membranes for Anion Exchange Membrane Water Electrolysis Systems

    University essay from KTH/Tillämpad elektrokemi

    Author : Parth Omprakash Dayama; [2021]
    Keywords : water electrolysis; membrane; electrocatalysts; anion exchange membrane; hydrogen; vattenelektrolys; membran; elektrokatalysatorer; anjonbytande membran; vätgas;

    Abstract : Vätgas kan framställas från förnybara energikällor genom vattenelektrolys med anjonbytande membran (AEMWE). AEMWE har vissa fördelar jämfört med traditionell alkalisk vattenelektrolys och elektrolysmed protonledande membran. READ MORE

  3. 17. Internal Combustion Engine Calibration considering the Embedded Systems Sensor Accuracy

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Daniel Rodríguez Pascual; [2021]
    Keywords : ;

    Abstract : In recent years, the increasing economic, environmental and legal demands on internal combustion engines to reduce emissions and fuel consumption are a major challenge.

  4. 18. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

    University essay from KTH/Materialvetenskap

    Author : Ziyi Shi; [2021]
    Keywords : graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

    Abstract : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.

  5. 19. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Per Kautto; [2020]
    Keywords : palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Abstract : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. READ MORE

  6. 20. Generation of Model NiMo Hydrotreating Nano-catalyst via the Spark Discharge Technique

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hatoon Makhool; [2020]
    Keywords : Model catalyst systems; hydrotreating catalysts; NiMo catalysts; Spark discharge technique; nanoparticles; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : Establishing a technically practical method to generate representative model catalysts for the use in characterizations and testing prior to catalyst implementation in chemical process units would allow for a more sophisticated understanding of the underlying catalytic mechanisms. As a step towards establishing such a method, generating non-agglomerated, spherical NiMo nanoparticles, with diameters below 25 nm and atomic composition of maximum 30 at% Ni with Mo (maximum 3:7 Ni:Mo atomic ratio), for application as model hydrotreating catalysts, was addressed.
