  1. 1. Calibration of Quenching for laser-induced fluorescence of CO₂ at 2.7 μm

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Philip Stjärneblad; [2019]
    Nyckelord :Laser-induced fluorescence; CO oxidation; Catalysis; Fluorescence quenching; Calibration; Physics and Astronomy;

    Sammanfattning : Knowledge about the gas-phase close to an active catalyst is essential in order to understand the properties of the catalytic reaction process. By the use of planar laser-induced fluorescence (PLIF), the gas-phase can be visualized with high spatial and temporal resolution without affecting the catalyst. LÄS MER

  3. 2. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Sebastian Pfaff; [2017]
    Nyckelord :plif; laser diagnostics; catalysis; carbon monoxide; carbon dioxide; palladium; planar laser induced fluorescence; Physics and Astronomy;

    Sammanfattning : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. LÄS MER

  4. 3. Setup and control of a test reactor for catalysis with optical access

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Christoffer Pichler; [2014]
    Nyckelord :Physics; Catalysis; Laser Induced Fluorescence; Mass spectrometer; Physics and Astronomy;

    Sammanfattning : CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. LÄS MER

  5. 4. Experimental Tools for Studies of Heterogeneous Catalysis - Development and Case Studies

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Jonas Evertsson; [2013]
    Nyckelord :X-ray Diffraction; PLIF; Planar Laser Induced Fluorescence; activity measurement; reactor; catalyst; catalytic processes; XRD; Mass spectrometry; Heterogeneous catalysis; Chemistry; Physics and Astronomy;

    Sammanfattning : In this project four reactors for studies of heterogeneous catalysis have been developed. They were tested using case studies, especially concerning methane oxidation over palladium. The test measurements showed that the reactors work or would work very well after slight modifications.
