  1. 1. Production of bioethanol from wheat straw hydrolysate using reverse membrane bioreactor (rMBR)

    Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Jessica Khin San; [2018]
    Nyckelord :Reverse membrane bioreactor; wheat straw; fermentation; ethanol; furfural; diffusion rate;

    Sammanfattning : The second-generation bioethanol production in which lignocellulosic material is used as feedstock faces some difficulties. Lignocellulosic materials have to be pretreated prior to fermentation. LÄS MER

  3. 2. 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.

  4. 3. Potential of Steam Pretreated Jerusalem Artichok Stem for Ethanol Production

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Eliasson; [2017]
    Nyckelord :SSF; Simultaneous Saccharification and Fermentation; Lignocellulose; Bioethanol; Second generation Bioethanol; Steam Explotion; Jerusalem Artichoke; Enzymatic Hydrolysis; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : To reach the goals set for the reduction of green house gas by the European Union the use of fossil fuels has to be reduced. To do this alternative fuels such as bioethanol have to substitute fossil fuels. LÄS MER

  5. 4. 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

  7. 5. Study on fungal pellet morphology and its industrial applications

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Vamsi Krishna Ravula; [2017]
    Nyckelord :Filamentous fungi; Ascomycetes; Edible fungi; Pellet; Neurospora intermedia;

    Sammanfattning : Mycelial pellet formation by filamentous fungi is one of the most researched topics in fungal biotechnology research. Pellets are generally formed as a result of a complex interaction process through the influence of many cultivation factors such as inoculum size, pH, dissolved oxygen level, agitation system, nucleating agents, additives, trace metals, CO2, temperature, reactor types, carbon substrate, rheology, culture modes, fermenter geometry, nitrogen and phosphate levels etc. LÄS MER
