  1. 1. Valorization Of Whole Stillage With Filamentous Fungi Cultivation Using Membrane Bioreactors

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

    Författare :Gülru Bulkan; [2018]
    Nyckelord :whole stillage; membrane bioreactor; filamentous fungi cultivation;

    Sammanfattning : A significant by-product of bioethanol plants is whole stillage, commonly used to produce animal feed due to its nutritious value, has a potential to be used to produce various value-added products while eliminating a costly process step is an alternative approach. In this study, production and separation of additional ethanol, fungal biomass and enzyme were successfully achieved with the cultivation in membrane bioreactors in batch process condition. LÄS MER

  3. 2. 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

  4. 3. From Waste to Bioethanol - A Feasibility Study on Animal Bedding

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ajsa Hodzic; Desirée Karlsson; [2017]

    Sammanfattning : For the year 2020, the European Union has set common goals to aim for regarding the environment. One of them being to reduce the green house gas (GHG) emissions by 20 percent. The world population is increasing, consequently increasing the demand for energy and food. LÄS MER

  5. 4. Combined production of bioethanol and biogas from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Victor Gustafson; [2015]
    Nyckelord :lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Sammanfattning : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. LÄS MER

  7. 5. Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Ayda Barid Babapour; Maryam Nadalipour Gavitar; [2012]
    Nyckelord :SSF; yeast; ethanol; lignocellulosic; fermentation; hardwood; lactic acid; pentose fermenting; contamination;

    Sammanfattning : Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.
