  1. 1. Machine Learning Prediction of Enzymes’ Optimal Catalytic Temperatures

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Camille Finlinson Porter; [2023-03-22]
    Keywords : enzyme; protein; amino acid; protein structure; optimal catalytic temperature;

    Abstract : Enzymes that have been genetically engineered to withstand high temperatures are used by industry to make products with less waste and pollution. Different features of protein structure affect the optimal catalytic temperature ("topt") at which enzymes catalyze reactions most efficiently. READ MORE

  3. 2. Effect of powder spray drying on catalyst formulation in tablet form

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Kajsa Wahlgren; [2023]
    Keywords : Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    Abstract : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. READ MORE

  4. 3. 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. 4. Exhaust Temperature Modeling and Optimal Control of Catalytic Converter Heating

    University essay from Linköpings universitet/Fordonssystem

    Author : Victor Petersson; [2019]
    Keywords : cold-start; catalyst heating; ignition retardation; GDI;

    Abstract : After reaching its light-off temperature, the catalytic aftertreatment system plays a major part in maintaining emissions at low levels for vehicles equipped with combustion engines. In this thesis, modelling of the exhaust gas temperature is investigated along with optimal control strategy for variable ignition and exhaust valve opening angles for optimal catalytic converter heating.

  6. 5. Catalytic hydrotreating of lignin

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Markus Lilja; [2019]
    Keywords : Lignin; hydrotreating; kemiteknik; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : One of the main challenge’s society faces today is climate change caused by CO2 due to the de-pendence on fossil fuels. To combat the increasing CO2 levels there is a need to develop renewable fuels. One such fuel could potentially be derived from lignin. In this thesis, lignin derived from a pulp and paper mill was first treated and cleaned. READ MORE
