1. 16. Strategies for improving kraftliner pulp properties

   Författare :Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. LÄS MER

3. 17. GASIFICATION-BASED BIOREFINERY FOR MECHANICAL PULP MILLS

   Författare :Jie He; Engstrand Per; Zhang Wennan; Olof Björkqvist; Dahlquist Erik; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Bio-fuels; Power Generation; Biomass Residues; ASPEN Plus;

   Sammanfattning : The modern concept of "biorefinery" is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various biobased products. LÄS MER

5. 19. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique

   Författare :Jenny Lindau; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; displacement washing; pulp properties.; measurement technique; compression; dispersion; fibre damage; local properties; kraft pulp;

   Sammanfattning : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. LÄS MER
