  2. 1. GASIFICATION-BASED BIOREFINERY FOR MECHANICAL PULP MILLS

    Author : Jie He; Engstrand Per; Zhang Wennan; Olof Björkqvist; Dahlquist Erik; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Bio-fuels; Power Generation; Biomass Residues; ASPEN Plus;

    Abstract : The modern concept of "biorefinery" is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various biobased products. READ MORE

  4. 2. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Author : Sara Jonsdottir Glaser; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Abstract : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries.

  5. 3. Pretreatment and Enzymatic Treatment of Spruce : A functional designed wood components separation for a future biorefinery

    Author : Yan Wang; Gunnar Henriksson; Mikael E. Lindström; Hans Theliander; Martin Lawoko; Adriaan van Heiningen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft cooking; extended impregnation; enzymes; chemo-enzymatic separation process; peeling reaction; sodium borohydride; polysulfide; anthraquinone; sodium dithionite; mild steam explosion; biorefinery.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter.

  6. 4. Towards molecular weight-dependent uses of kraft lignin

    Author : Ayumu Tagami; Mikael Lindström; Olena Sevastyanova; Anna Wistrand; Stefan Backa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; successive solvent fractionation; molecular weight; structural analysis; thermal stability; heat capacity; antioxidant activity; methylene blue sorption; tunicate cellulose nanofiber-starch lignin composites films; film properties; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. READ MORE

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

    Author : Marie Linde; Avdelningen 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
