  1. 6. Chemical kinetics and transport of tropospheric trace compounds - implications for environment and air quality

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

    Author : Stina Ausmeel; [2015]
    Keywords : Physics and Astronomy;

    Abstract : Fourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). READ MORE

  2. 7. UV pretreatment of Alkaline Bleaching Wastewater from a Kraft Pulp and Paper Mill prior to Anaerobic Digestion in a Lab scale UASB Reactor

    University essay from Tema vatten i natur och samhälle; Filosofiska fakulteten

    Author : Marielle Karlsson; [2013]
    Keywords : Anaerobic digestion; biogas; UV pretreatment; UV H2O2; UASB; EOP wastewater; lignin; kraft pulp and paper mill;

    Abstract : The effects of UV pretreatment on alkaline bleaching (EOP) wastewater from a kraft pulp and paper mill were investigated prior to anaerobic digestion (AD) in an upflow anaerobic sludge blanket (UASB) reactor. The aim was to enhance the methane production, increase the reduction of total organic carbon (TOC) and determine the best UV exposure time. READ MORE

  3. 8. Atmospheric Fate of Methyl Bromide

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

    Author : Magnus Joelsson; [2012]
    Keywords : Methyl bromide; ozone; Earth and Environmental Sciences;

    Abstract : Den fotokemiska reaktorn vid Copenhagen Centre for Atmospheric Research, Köpenhamns universitet, har i denna studie används för att bestämma nya värden på hastighetskonstanterna k(i) för reaktionen: CH3Br + OH -> produkter (i) och k(ii) för reaktionen: CH3Br + O(1D) -> produkter. (ii) Radikalerna (O(1D) och OH) framställdes i studien genom att fotolysera ozonmolekyler med UV-C-ljus. READ MORE

  4. 9. TREATMENT OF ODOROUS VOLATILE ORGANIC COMPOUNDS USING UV/H2O2

    University essay from KTH/Energiprocesser

    Author : Manases Fuh Nguo; [2011]
    Keywords : ;

    Abstract : Odorous volatile organic compounds emissions from fried-food industries posed severed pollution problems both to the workers and the surrounding inhabitants. These industries need to look for cost effective and efficient methods to reduce these emitted gases. READ MORE

  5. 10. Advanced Ray Tracing Techniques for Simulation of Thermal Radiation in Fluids

    University essay from KTH/Mekanik; KTH/Linné Flow Center, FLOW

    Author : Bernhard Semlitsch; [2010]
    Keywords : Thermal radiation; Solar radiation; Solar energy; Heat transfer;

    Abstract : For modeling thermal heat transfer, not only the effects of convection and conduction are relevant, but also thermal and visible radiation. Radiation is especially important for setups with large temperature differences, as well as for interaction with external light sources. READ MORE
