1. 16. Absorbent Materials from Kraft Pulp

   Författare :Fredrik Wernersson Brodin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention; MFC; oxidation; Absorbent; absorption; TEMPO; freeze drying; disintegration;

   Sammanfattning : SuperAbsorbent Polymers (SAPs) have, since being introduced in the 1980s, become an important constituent in hygiene products, such as disposable diapers. The design of disposable diapers has changed over the years and today thinner products can be produced partly because of the excellent absorption and retention properties of the petrochemical-based SAPs.

3. 17. Mechanical Pulp Based Nano-ligno-cellulose : Production, Characterisation and their Effect on Paper Properties

   Författare :Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Kristin Syverud; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose NLC ; handsheets; strength properties; crill;

   Sammanfattning : Almost all research on biorefinery concepts are based on chemical pulping processes and ways of utilising lignin, hemicelluloses and extractives as well as a part of the remaining cellulose for production of nano materials in order to create more valuable products than today. Within the Forest as a Resource (FORE) research program at FSCN we are utilising the whole chain of unit processes from forestry to final products as paper and board, where the pulping process research focus on high yield process as TMP and CTMP.

4. 18. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol

   Författare :Rickard Fornell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; energy efficiency; process integration; biofuels; kraft pulp mill; ethanol;

   Sammanfattning : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. LÄS MER

7. 20. 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
