  1. 1. Catalytic conversion of LignoBoost Kraft lignin into liquid products in near-critical water

    Författare :Huyen Nguyen Lyckeskog; Chalmers University of Technology; []
    Nyckelord :LignoBoost; Catalytic conversion; Hydrothermal conversion; Bio-oil; Near-critical water; Lignin;

    Sammanfattning : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Due to its aromatic nature, lignin is recognized as being a potential feedstock for producing transportation fuel and high value-added chemicals. LÄS MER

  2. 2. Towards a pure kraft lignin

    Författare :Rufus Ziesig; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; black liquor; lignin; impurities; purification; carbohydrate; inorganics; precipitation;

    Sammanfattning : The most widely used production method for paper pulp in the world is kraft pulping. In chemical pulping the polymer, lignin, which binds the wood fibres together, is partly depolymerized. This allows the wood fibres to be separated from each other. LÄS MER

  3. 3. Lignin Extraction from Black Liquor - Precipitation, filtration and washing

    Författare :Henrik Wallmo; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filtration; Precipitation; Washing; Lignin; Absorption; Separation; LignoBoost.; Black liquor;

    Sammanfattning : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. LÄS MER

  4. 4. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength

    Författare :Julie Durruty; Chalmers University of Technology; []
    Nyckelord :acid precipitation.; LignoBoost process; compressible filter cake; particle interactions; xylan; softwood lignin; constitutive relationships; local filtration properties; dead-end filtration;

    Sammanfattning : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.

  5. 5. On the local filtration properties during cake filtration: Studies on LignoBoost lignin and the influence of ionic strength

    Författare :Julie Durruty; Chalmers University of Technology; []
    Nyckelord :LignoBoost process; local filtration properties; dead-end filtration; softwood lignin; particles interactions; compressible filter cake; constitutive relationships;

    Sammanfattning : The Kraft pulping technology has been thoughtfullyinvestigated and developed over the pasthundred years and more; it is currently the mostcommonly-used method ofpulping in the world. Anew and promising opportunity for Kraft pulp millswould be to take a step towards becomingbiorefineries by implementing technologies ableto extract and convert the organic by-products,such as lignin, into a wide rangeof value-added products and chemicals.
