    Abstract : Enzymes are gaining increasing importance as catalysts for selective transformations in organic synthetic chemistry. The engineering and design of enzymes is a developing, growing research field that is employed in biocatalysis. READ MORE

  3. 3. Activation of dissolving pulps prior to viscose preparation

    Author : Niklas Kvarnlöf; Ulf Germgård; Leif J. Jönsson; Carl-Axel Söderlund; Herbert Sixta; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; dissolving pulp; enzyme; reactivity; viscose; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : The conventional viscose manufacturing process is a mature process that needs to be improved with respect to its environmental impact and its production cost structure. Therefore a research study has been done with the aim to improve the reactivity of the dissolving pulp used, in order to reduce the chemical demand in the viscose process and thus reduce the cost and indirectly the environmental impact.

    Abstract : The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter.
