  4. 4. 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

  5. 5. 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 Linköpings universitet/Tema vatten i natur och samhälleLinköpings universitet/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
