  1. 1. Assessing the sustainability of bioethanol production in Nepal

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dilip Khatiwada; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bioethanol; sustainability; life cycle assessment; net energy values; greenhouse gas GHG balances; sustainable development; least developed countries LDCs ; Nepal; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Climatology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Klimatologi;

    Abstract : Access to modern energy services derived from renewable sources is a prerequisite, not only for economic growth, rural development and sustainable development, but also for energy security and climate change mitigation. The least developed countries (LDCs) primarily use traditional biomass and have little access to commercial energy sources. READ MORE

  2. 2. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood

    University dissertation from Professor Guido Zacchi, Department of Chemical Engineering 1, Lund University

    Author : Charlotte Tengborg; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recirculation of process streams; detoxification; inhibition; hydrolysis conditions; enzymatic hydrolysis; Ethanol production; steam pretreatment; softwood; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Abstract : The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. READ MORE

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

    University dissertation from Borås : Högskolan i Borås

    Author : Osagie Alex Osadolor; Högskolan i Borås.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; bioreactor; bioreactor design; techno-economic analysis; membrane stress analysis; mass transfer; hydrodynamics; Resource Recovery; Resursåtervinning;

    Abstract : 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. READ MORE

  4. 4. The Development of Bioethanol Markets under Sustainability Requirements

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Henrique Pacini; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Biofuels; Consumer choice; Sustainability Criteria; International Trade; European Union; Brazil; Sweden; Policy.; Energiteknik; Energy Technology;

    Abstract : This thesis is a theoretical and empirical examination of the developmentof bioethanol markets since 2005 when sustainability regulations forbiofuels were introduced globally. The experiences of Brazil and Sweden,and the influence of European regulations on the development ofbioethanol markets receive special attention. READ MORE

  5. 5. Lignocellulosic Ethanol Production Potential and Regional Transportation Fuel Demand

    University dissertation from Västerås : Mälardalens högskola

    Author : Lilia Daianova; Mälardalens högskola.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. READ MORE
