  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  3. 2. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

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

    Author : Cecilia Zambelli; [2023]
    Keywords : ;

    Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  4. 3. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Adam Jacobsson Trönndal; [2023]
    Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

  5. 4. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mathias Schmekel; [2023]
    Keywords : Model predictive control; Selective catalytic reduction; Nitrogen oxides; Modell-prediktiv reglering; Selektiv katalytisk reduktion; Kväveoxider;

    Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

  6. 5. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE
