  1. 11. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

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

    Author : Henrik Johansson; [2018]
    Keywords : Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Abstract : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. READ MORE

  2. 12. Health Risks of VOCs and Aldehydes in Indoor Air : A Case Study of Three Beauty Salons and a Gym

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Danielle Ydstål; [2016]
    Keywords : ;

    Abstract : People tend to spend more and more time indoors, constantly breathing indoor air. In indoor air there is a mixture of chemicals from both the outdoor air, which is let in through the ventilation systems, and from the materials and products that are used indoors. READ MORE

  3. 13. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Emelie Graham; [2015]
    Keywords : Ecosystem Science; Physical Geography; 2nd generation biofuels; furans; tropospheric chemistry; ozonolysis; atmospheric kinetics; computational chemistry; IR Spectroscopy; Atmospheric Science Biochemical Cycles; Earth and Environmental Sciences;

    Abstract : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. READ MORE

  4. 14. Unregulated Emissions from Heavy-Duty Engines and Vehicles

    University essay from KTH/Fordonsdynamik

    Author : Edvin Tang; Toni Zalem; [2014]
    Keywords : ;

    Abstract : Road transport emission levels are at an all-time low and post Euro VI regulations are now up for discussion. A literature study of unregulated diesel emissions in Europe; CO2, N2O, NO2, CH4 and aldehydes has been made to determine the effects and importance of the emissions in today´s heavy-duty vehicles.
