  1. 21. Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF

    Författare :Marie Linde; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbochemistry; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolism; Biokemi; Metabolism; Biochemistry; Barley straw; Wheat straw; DDGS; Fermentation; SSF; Enzymatic hydrolysis; H2SO4; Ethanol production; Steam pretreatment; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen; Wood; pulp and paper technology; Pappers- och massateknik; Biotechnology; Bioteknik;

    Sammanfattning : Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. LÄS MER

  3. 22. Process development and environmental assessment within softwood based biorefineries

    Författare :Karin Carlqvist; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar platform; extractives; steam explosion; pretreatment; bark; enzymatic hydrolysis; phenolic compounds; bioeconomy; LCA; Pinus sylvestris; Picea abies; pine; spruce; sockerplattform; extraktivämnen; Steam explosion SE ; förbehandling lignocellulosa; bark; enzymatisk hydrolys; fenoler; bioekonomi; LCA; Pinus sylvestris; Picea abies; tall; gran;

    Sammanfattning : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).

  4. 23. Enzymatic Synthesis of Alkyl Glycosides. New Applications for Glycoside Hydrolases

    Författare :David Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGTase; cyclodextrin glycosyltransferase; alkyl glycoside; enzyme stabliity; enzymatic synthesis; enzyme immobilisation; surfactant; glycosylation;

    Sammanfattning : The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. LÄS MER

  5. 24. Waste Textiles Bioprocessing to Ethanol and Biogas

    Författare :Azam Jeihanipour; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery; waste textile.;

    Sammanfattning : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. LÄS MER

  7. 25. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

    Författare :Andreas Rudolf; Institutionen 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
