  1. 1. Isobutanol - An alternative biofuel for hand-held petrol products

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Jens Janssen; [2018]
    Nyckelord :Isobutanol; biofuel; emission; two-stroke;

    Sammanfattning : Pollution and environmental concerns require further improvements in engine technologyas well as research of alternative fuels. Users of handheld products are directlyexposed to the exhaust gas and thus to the occurring emissions, which cancause significant damage. Pursuing to reduce emissions is therefore a vital task.

  3. 2. Gasoline‐Ethanol‐Methanol (GEM) Ternary Fuel Blend as an Alternative Passenger Car Fuel in Sweden

    Master-uppsats, KTH/Energi och klimatstudier, ECS

    Författare :Sebastiaan Nikolas Tsirakos; [2017]
    Nyckelord :GEM fuel; Biofuels; Sweden; Bioenergy; Methanol; 2nd generation Ethanol; Black Liquor Gasification; Gasoline‐Ethanol‐Methanol GEM ternary blend; Distribution Network Biofuels; E85 Flexible Fuel Vehicles; Forestry Residue Fermentation;

    Sammanfattning : This paper discusses the potential of gasoline, ethanol and methanol ternary blend as an alternative passenger car fuel in Sweden. Sweden has set various targets aimed to reduce its GHG emissions and to increase the share of renewables in the transportation sector. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emelie Graham; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Environmental and socioeconomic assessment of rice straw conversion to ethanol in Indonesia : The case of Bali

    Master-uppsats, KTH/Energi och klimatstudier, ECS

    Författare :Victor Samuel; [2013]
    Nyckelord :rice straw-to-ethanol conversion; second-generation biofuel; employment creation; lifecycle GHG reduction;

    Sammanfattning : The vast rice production in some developing Asian countries like Indonesia raises expectation on poverty alleviation and energy diversification through second generation biofuel production from rice residues, specifically rice straw. This work attempts to estimate the potential environmental and socioeconomic benefits of rice straw-to-ethanol project in Indonesia. LÄS MER

  7. 5. Potential for cultivation of Miscanthus x Giganteus for biofuel production in different climate zones : with a changing climate and limited water resources

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Erik Tobin; Linnéa Tjernström; [2013]
    Nyckelord :biofuel; miscanthus; global warming; CoupModel; water balance; energy crop;

    Sammanfattning : Miscanthus Giganteus is a rapidly growing perennial grass utilizing C4 photosynthesis that is a promising candidate as a raw resource for “second generation” biofuel production. This study seeks to determine the long-term sustainability, from a water balance perspective, of cultivating this plant in different climate zones. LÄS MER
