  1. 1. Isoconversional analysis for the prediction of mass-loss rates during pyrolysis of biomass

    Författare :Lina Norberg Samuelsson; Matthaus Babler; Rosana Moriana; Henrik Wiinikka; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; biomass; kinetics; cellulose; spruce; black-liquor; model-free; isoconversional; prediction; pyrolys; biomassa; kinetik; cellulosa; gran; svartlut; model-free; isoconversional; förutsägelse; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : Biomass is the only renewable carbon source that can compete with fossil energy sources in terms of production of materials, chemicals and fuels. Biomass can be transformed into charcoal, liquid and gas through pyrolysis, i.e. pure thermal decomposition. LÄS MER

  3. 2. Pyrolysis and Detoxification of Waste Electrical and Electronic Equipment (WEEE) for Feedstock Recycling

    Författare :Panagiotis Evangelopoulos; Weihong Yang; Efthymios Kantarelis; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; WEEE; solvent extraction; brominated flame retardants; Tetrabromobisphenol A; Auger reactor; Πυρόλυση; ΑΗΗΕ; εκχύλιση με διαλύτη; βρωμιωμένα επιβραδυντικά φλόγας; Τετραβρωμοδιφαινόλη Α; Pyrolys; WEEE; lösningsmedelsextraktion; bromerade flamskyddsmedel; tetrabrombisfenol A; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The trends in waste electrical and electronic equipment (WEEE) generation shows that their volume constantly increases, while the current waste management technologies have proven to be insufficient in order to meet the strict criteria and the new legislations of the European Union. Pyrolysis and thermal treatment in general could be a valuable solution for closing the loop of materials and could contribute to the energy demands of modern society. LÄS MER
