  2. 2. Hydrothermal Liquefaction of Lignin into Bio-Oil

    Författare :Huyen Nguyen Lyckeskog; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrothermal conversion; aging; bio-oil; stability; subcritical water; lignin;

    Sammanfattning : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Nowadays, most of the lignin (almost 99%) produced in the Kraft pulping process is used as internal fuel. LÄS MER

  3. 3. Precipitation and separation of lignin from kraft black liquor

    Författare :Fredrik Öhman; Chalmers University of Technology; []
    Nyckelord :pressing; filtration; washing; lignin; separation; precipitation; black liquor; extraction;

    Sammanfattning : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. LÄS MER

  4. 4. LIGNIN HYDROTHERMAL LIQUEFACTION IN SUBCRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS

    Författare :Tallal Belkheiri; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Biomass valorisation; base depolymerisation; biofuel; lignin; green chemicals.;

    Sammanfattning : Lignin is one of the most abundant amorphous macromolecules found in nature. Along with cellulose and hemicellulose, it forms a main component of biomass, and is mainly responsible for providing strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. LÄS MER

  5. 5. LIGNIN DEPOLYMERISATION IN NEAR- CRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS: EFFECT OF CO-SOLVENT AND pH

    Författare :Tallal Belkheiri; Chalmers University of Technology; []
    Nyckelord :green chemicals; biofuel; lignin; catalytic degradation; Biomass valorisation; hydrogen donor; base depolymerisation;

    Sammanfattning : Lignin is a complex three-dimensional amorphous polymer, which, along with cellulose and hemicellulose, forms a main component of biomass. Its main role is in giving strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. LÄS MER
