  1. 11. Strategies for improving kraftliner pulp properties

    Author : Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 12. Chemical Properties and Thermal Behaviour of Kraft Lignins

    Author : Ida Brodin; Göran Gellerstedt; Elisabeth Sjöholm; Hans Theliander; Ulrica Edlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi;

    Abstract : Research concerning lignin has increased during the last years due to its renewability and ready availability in black liquor at pulp mills. Today, the kraft lignin found in black liquor is used as a fuel to gain energy in the recovery boiler at the mill. READ MORE

  3. 13. The Use of Membrane Filtration to Improve the Properties of Extracted Wood Components

    Author : Mikaela Helander; Mikael E. Lindström; Arthur J. Ragauskas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The forest is alarge and important natural resourcein Sweden, and approximately 70% of the country’s land area is woodland. Wood is an excellent raw material for the replacement of oil-based products because it is renewable, biodegradable and carbon neutral. READ MORE

  4. 14. On calcium-related problems in kraft pulping of Eucalyptus dunnii

    Author : Vijaya Lakshmi Vegunta; Olena Sevastyanova; Helena Håkansson; KTH; []
    Keywords : Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Kraft pulping is the most widely used pulping process for producing chemical pulp today. It has been in use for more than 130 years. READ MORE

  5. 15. Characterization of Spruce Xylan and Its Potential for Strength Improvement

    Author : Zheng Jansson; Elisabet Brännvall; Mikael Lindström; Hannes Vomhoff; Ulrica Edlund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylan; paper strength;

    Abstract : Xylan dissolved during kraft cooking and later redeposited on fibre surfaces has been shown to give higher pulp yield and better strength properties. This is economically interesting from an industrial point of view. READ MORE
