  1. 16. 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

  2. 17. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

    Author : Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Advanced wastewater treatment; WWTP; pilot plant; pharmaceutical residues; removal of pharmaceuticals; activated carbon; ozonation; nanofiltration; biomarker; Baltic Sea; Bioteknologi; Biotechnology;

    Abstract : Pharmaceutical residues are found in the environment due to extensive use in human and veterinary medicine. The active pharmaceutical ingredients (APIs) have a potential impact in non-target organisms. Municipal wastewater treatment plants (WWTPs) are not designed to remove APIs. READ MORE

  3. 18. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine

    Author : Isabelle Simonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomaterials; Surface chemistry; Ion specific effects; MOF synthesis; Odor control; Adsorption; Synthetic urine;

    Abstract : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. READ MORE

  4. 19. Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes

    Author : Patric Lindahl; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; atomic ratio; environmental samples; nuclear weapons fallout; Chernobyl fallout; bioindicators; activated carbon; Sellafield; plutonium; neptunium; ICP-MS; technetium;

    Abstract : Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. READ MORE

  5. 20. Molasses Purification and Valorisation : Towards a sustainable production of hydroxymethylfurfural

    Author : Mikael Sjölin; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar beet molasses; 5-hydroxymethylfurfural; membrane filtration; hydrolysis; dehydration; adsorption; purification; solvent regeneration;

    Abstract : The industrial transition from petrochemical-based to a more sustainable and circular economy requires the utilisation of renewable biobased raw materials that do not compete with other important industries, such as the food sector, preferably wastes or low value by-products. 5-hydroxymethylfurfural (HMF) is a versatile platform chemical that has great potential for utilisation in various sectors in a future bioeconomy, as it can be produced from sugars.
