2. 1. 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

4. 2. Enhancing the circular economy: Resource recovery through thermochemical conversion processes of landfill waste and biomass

   Author : Ilman Nuran Zaini; Weihong Yang; Pär Jönsson; Ashwani K. Gupta; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; pyrolysis; waste-to-energy; landfill waste; hydrogen production; circular economy; municipal solid waste; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Currently, the global economy looses a considerable amount of potential secondary raw materials from the disposed waste streams. Furthermore, the existing landfill sites that often do not have proper environmental protection technologies pose a long-lasting risk for the environment, which urge immediate actions for landfill remediations.

5. 3. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production

   Author : Devy Kartika Ratnasari; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-MCM-41; lignocellulose biomass; H-ZSM-5; kinetic study; catalyst regeneration;

   Abstract : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. READ MORE

6. 4. Sustainable Lubrication and Tribotronics enabled by Ionic Materials

   Author : Akepati Bhaskar Reddy; Sergei Glavatskih; Mark W. Rutland; Nicholas Spencer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable lubrication; ionic liquid; tribotronics; lubricating grease; neutron reflectance; Machine Design; Maskinkonstruktion;

   Abstract : Developments in machine design play a crucial role in the global endeavor towards sustainability. The potential for energy conservation and emission reduction has pushed lubrication research to the forefront, with the lubricant considered to be a vital machine component. READ MORE

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

   Author : Lina Norberg Samuelsson; Matthaus Babler; Rosana Moriana; Henrik Wiinikka; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE
