  1. 11. Design and development of a novel textile based bioreactor: : Ethanol and biogas production as case studies

    Författare :Osagie Alex Osadolor; Christian Larroche; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; bioreactor; bioreactor design; techno-economic analysis; membrane stress analysis; mass transfer; hydrodynamics; Resource Recovery; Resursåtervinning;

    Sammanfattning : Bioreactors are designed to provide enabling conditions for the controlled growth of microorganisms, such as good heat and mass transfer, aeration, hydrodynamics, geometry for adequate gas holdup, pH and foaming control, conditions for optimal substrate consumption and product formation, as well as mechanisms for monitoring microbial conditions. Additionally, bioreactors are designed to handle stress that would be exerted on them by the weight of the fermenting media and by the high pressure used for sterilisation. LÄS MER

  3. 12. Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings

    Författare :Benny Palmqvist; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulose; Bioethanol; High solid loadings; Biomass rheology; Enzymatic hydrolysis; Simultaneous Saccharification and co-Fermentation;

    Sammanfattning : Fuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. LÄS MER

  4. 13. Integrated starch and lignocellulose based biorefineries : Synergies and opportunities

    Författare :Michael Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process integration; Fermentation; Hydrolysis; Lignocellulosic Biomass; Wheat grain; Bioethanol;

    Sammanfattning : The transition from a reliance on fossil resources to the use of renewables for the production of energy, fuels and chemicals is essential for ensuring the sustainability of continued human development. Plant-based biomass is a renewable resource which can be transformed into all of these products. LÄS MER

  5. 14. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

    Författare :Andreas Rudolf; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Fermentation; Lignocellulose; Hydrolysis; Bioethanol;

    Sammanfattning : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. LÄS MER

  7. 15. Assessing the sustainability of bioethanol production in different development contexts: A systems approach

    Författare :Dilip Khatiwada; Semida Silveira; Faaij André; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioenergy and biofuel; bioethanol industry; development trend; sustainability assessment; climate change mitigation; energy security; life cycle assessment; systems optimisation; bioenergi och biobränsle; bioetanolindustri; utvecklingstrender; hållbarhetsbedömning; motverka klimatförändringar; energisäkerhet; livscykelanalys; systemoptimering; SRA - Energy; SRA - Energi;

    Sammanfattning : The continuous depletion of fossil fuel reserves, the global agenda on climate change and threats to energy security have led to increased global interest in the exploration, production and utilisation of bioenergy and biofuels. Access to modern bioenergy carriers derived from the efficient conversion of locally available biomass resources is indispensable for economic growth, rural development and sustainable development in developing countries.
