  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. Acoustic Characterization of Catalyst

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Surachit Dokson; [2023]
    Keywords : ;

    Abstract : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. READ MORE

  4. 3. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

  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.
