  1. 11. Chemical Properties and Thermal Behaviour of Kraft Lignins

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

    Sammanfattning : 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. LÄS MER

  3. 12. Thermoset resins using technical lignin as a base constituent

    Författare :Marcus Jawerth; Mats Johansson; Heikki Tenhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The need to find sustainable paths for our society is imminent to tackle environmental concerns of today. The majority of all plastic materials are produced from crude oil but in the future a much larger portion must originate from renewable resources to address some of these problems. LÄS MER

  4. 13. LIGNIN DEPOLYMERISATION IN NEAR- CRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS: EFFECT OF CO-SOLVENT AND pH

    Författare :Tallal Belkheiri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green chemicals; biofuel; lignin; catalytic degradation; Biomass valorisation; hydrogen donor; base depolymerisation;

    Sammanfattning : Lignin is a complex three-dimensional amorphous polymer, which, along with cellulose and hemicellulose, forms a main component of biomass. Its main role is in giving strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. LÄS MER

  5. 14. LIGNIN HYDROTHERMAL LIQUEFACTION IN SUBCRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS

    Författare :Tallal Belkheiri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass valorisation; base depolymerisation; biofuel; lignin; green chemicals.;

    Sammanfattning : Lignin is one of the most abundant amorphous macromolecules found in nature. Along with cellulose and hemicellulose, it forms a main component of biomass, and is mainly responsible for providing strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. LÄS MER

  7. 15. Mechanisms of Biopolymer Solvation: Development of a two-component ionic liquid solvent system

    Författare :Susanne Bylin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ionic liquids; solvation; mechanism; xylan; lignin; cellulose; wood components;

    Sammanfattning : Ionic liquids are of potential interest in the processing of lignocellulosic biomass, and/or its components, for the purpose of producing renewable and value-added biomaterials. An understanding of how solvation can be achieved and the way in which the feedstock biopolymers are affected, however, needs to be gained prior to a viable implementation. LÄS MER
