  2. 1. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard

    Author : Wen Jiang; Stergios Adamopoulos; Sheikh Ali Ahmed; Sergej Medved; Carsten Mai; Johannes Konnerth; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bark; Catalysts; Industrial side-streams; Liquefaction; Oat husks; Optimization; Particleboards; Polyurethane; Polyhydric alcohols; Wood adhesives; Wood sawdust; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

  5. 3. Hydrothermal Liquefaction of Kraft Lignin - The influence of capping agents and residence time

    Author : Anders Ahlbom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HTL; hydrothermal liquefaction; isopropanol; residence time; kraft lignin;

    Abstract : In the context of exploring alternatives to replace fossil resources, lignin has been acknowledged as a renewable source of various aromatic compounds that have the potential of being precursors to chemicals as well as fuel additives. Originating from lignocellulosic biomass such as wood, lignin is an amorphous polymer with a high content of aromatic units and, in order to harness these units, it must be depolymerised. READ MORE

  6. 4. Hydrothermal Liquefaction of Lignin into Bio-Oil

    Author : Huyen Nguyen Lyckeskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrothermal conversion; aging; bio-oil; stability; subcritical water; lignin;

    Abstract : 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. READ MORE
