    Author : Sören Halvarsson; Håkan Edlund; Magnus Norgren; Thomas Amidon; Mittuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Rice; Wheat; Straw; MDF; HDF; UF; MUF; MDI; Non-resin; binderless MDF; Ash; Silicon; SEM; Hot-pressing; MOR; MOE; IB; Thickness swelling; MDF properties; fibre swelling; WRV; Refining; Defibration.; NATURAL SCIENCES; NATURVETENSKAP; Chemical engineering; Kemiteknik; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

    Abstract : The purpose of this thesis was to develop an economical, sustainable, and environmentally friendly straw Medium Density Fibreboard (MDF) process, capable of full-scale manufacturing and to produce MDF of requested quality. The investigated straw was based on wheat (Triticum aestivum L.) and rice (Oryzae sativa L.). READ MORE

  2. 2. Development of integrated cellulose- and starch-based ethanol production and process design for improved xylose conversion

    Author : Borbala Erdei; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; wheat straw; wheat; first-generation ethanol; second-generation; integrated process; SSF; simultaneous saccharification and co-fermentation; xylose fermentation; S. cerevisiae TMB3400;

    Abstract : Transportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of second-generation bioethanol from lignocellulose (2G).

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

    Author : Marie Linde; Institutionen för kemiteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

    Author : Cristhian Carrasco; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

    Abstract : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. READ MORE

  5. 5. Integration of first and second generation bioethanol processes using edible filamentous fungus Neurospora intermedia

    Author : Ramkumar B Nair; Högskolan i Borås; []
    Keywords : First- and second-generation bioethanol; Integration; Neurospora intermedia; Edible filamentous fungi; Wheat straw; Wheat bran; Whole stillage fiber; Biochemistry; Biokemi;

    Abstract : Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. READ MORE
