  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.

  4. 2. Modelling of the pyrolysis of large wood particles

    Author : Michel Bellais; Krister Sjöström; Björn Zethraeus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; modelling; pyrolysis; shrinkage; wood; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Wood is an interesting alternative to fossil fuels. It is CO2-neutral and widely available. However it is a difficult fuel to handle which features a low energy content. Thus technologies for wood thermal conversion need to be improved. READ MORE

  5. 3. Wood hydrolysate Barriers

    Author : Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

    Abstract : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. READ MORE

  6. 4. Particles from biomass combustion -Characteristics and influence of additives

    Author : Linda S Bäfver; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; particle emission; wood; biomass; cereals; wood pellets;

    Abstract : AbstractHigh particle concentration in the air is a health risk, and particles from domestic biomass combustion are a significant particle source. In larger boilers, particles are an important element in the build-up of deposits on heat transfer surfaces, causing increased operation and maintenance costs. READ MORE

  7. 5. Phenolic Antioxidants in Wood Smoke

    Author : Jennica Kjällstrand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smoke; benzene; methoxyphenols; antioxidants; wood; lignin; combustion; biomass;

    Abstract : Smoke from residential wood burning constitutes a complex mixture of organic compounds with varying environmental and health effects. This thesis focuses on antioxidants and aromatic hydrocarbons emitted from small-scale burning. READ MORE
