  1. 16. Carbon Fibres from Kraft Lignin

    Författare :Ida Norberg; Monica Ek; Elisabeth Sjöholm; Göran Gellerstedt; Falk Liebner; KTH; []
    Nyckelord :;

    Sammanfattning : Kraft lignin has a high potential for use in more valuable applications than its current use as fuel in pulp mills and integrated pulp and paper mills. The possibility of using kraft lignin, a green material with a carbon content of more than 60 %, for the manufacturing of carbon fibres was investigated in this thesis. LÄS MER

  3. 17. Network Disruption and Turbulence in Fibre Suspensions

    Författare :Sven Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transition; friction; refractive index matching; Laser Doppler Anemometry LDA ; boundary-layer; Computational Fluid Dynamics CFD ; medium consistency MC ; network strength; fluidisation; pulp; suspension; fibres;

    Sammanfattning : The production of paper pulp involves the handling of large quantities of fibre suspensions. Today's call for energy efficiency and environmentally sound processes has led to the development of MC (Medium Consistency) technology. LÄS MER

  4. 18. Network Modelling for Evaluation of Mechanical Properties of Cellulose Fibre Fluff

    Författare :Susanne Heyden; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; fracture; fibres; computer simulation; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : A network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. LÄS MER
