1. 1. 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

3. 2. Ozone oxidation of fatty acid thin films: a TIR Raman study

   University essay from KTH/Yt- och korrosionsvetenskap

   Author : Frida Preuss; [2022]
   Keywords : ozone oxidation; TIR Raman; fatty acid; vibrational spectroscopy; thin film formation; ozonoxidation; TIR Raman; fettsyra; vibrationsspektroskopi; skapande av tunna filmer;

   Abstract : Detta examensarbete initierades och handledes av Mellifiq, ett företag som arbetar med rening av luft och vatten, där en applikation är rening av köksfrånluft med ozon. Ozon förhindrar att fettpartiklar i frånluften ansamlas på väggarna i kanalen och värmeväxlaren, vilket leder till högre brandsäkerhet och mer effektiv användning av värmeväxlaren. READ MORE

4. 3. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

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

   Author : Dana Lüdemann; [2020]
   Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

   Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

5. 4. Water blow out phenomena inside a heavy truck silencer

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

   Author : Rohit Suram Venkata Subramaniyam; [2020]
   Keywords : Water blow out in after treatment devices; Dew point strategy; Exhaust after treatment system; NOx sensors; Water formation in the exhaust; Vatten blåser in efter behandlingsanordningar; Daggpunktsstrategi; Avgas efter behandlingssystem; NOx-sensorer; Vattenbildning i avgaserna;

   Abstract : NOx sensors have become salient components in the development of efficient exhaust after treatment system for heavy duty vehicles in the past few years. When the accumulated water inside the silencer splashes on to the NOx sensor, it can cause permanent cracks in the sensor. READ MORE

6. 5. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Anton Åkervall; [2020]
   Keywords : DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

   Abstract : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). READ MORE
