  2. 1. Comparison of incineration and pyrolysis of NMC-lithium-ion batteries – determination of the effects on the chemical composition, and potential formation of hazardous by-products

    Author : Gabriele Lombardo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; vacuum; recycling; carbothermal; Keywords: Lithium-ion batteries; incineration; pyrolysis.;

    Abstract : Several industrial lithium battery recycling processes use thermal pre-treatment in an oxidative or inert atmosphere, or in a vacuum, to separate the battery components and remove organic material. However, a comparison of these pre-treatments on the microstructure and composition of waste material and production scrap LiBs has not been explored as well as there is a scarcity of information about the character of by-products generated during the processing.

  4. 2. Catalytic pyrolysis of lignin to produce fuels and functional carbon materials

    Author : Tong Han; Weihong Yang; Pär Jönsson; Anker Jensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin; Catalytic Pyrolysis; Biooil; Hydrogen; Magnetic Activated Carbon; Lignin; katalystisk pyrolys; bioolja; vätgas; magnetiskt aktiverat kol.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Development of renewable energy carriers and green adsorbents is an essential step in creating a fossil-free and toxin-free future of the world. Lignin is the second highest component of biomass and the only renewable resource of aromatics in nature. READ MORE

  5. 3. Fire behaviour of selected polymeric materials : Numerical modelling and validation using microscale and bench scale test methods

    Author : Abhishek Bhargava; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAEM; pyrolysis modelling; Polymer flammability; mass loss rate; Heat release rate HRR ;

    Abstract : The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. READ MORE

  6. 4. Waste-integrated biorefineries : A path towards efficient utilization of waste

    Author : Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. READ MORE

  7. 5. Wood chips for kraft and sulfite pulping : evaluation of novel forest-industrial drum-chipping technology

    Author : Jessica Gard Timmerfors; Leif J. Jönsson; David Blomberg; Sören Östlund; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood chip; drum chipper; impregnation; pulping; sulfite process; kraft process; Scots pine; Norway spruce; heartwood; frozen wood; moisture content;

    Abstract : Wood chipping and the supply of high-quality wood chips are of critical importance for most forest-industrial processes. The quality of wood chips affects product yield, product quality, and processability. READ MORE
