  1. 1. Off-gassing from thermally treated lignocellulosic biomass

    Författare :Eleonora Borén; Markus Broström; Sylvia H. Larsson; Peter Björklund; Lorenz Gerber; Henrik Antti; Capucine Dupont; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; steam explosion; enclosed storage; CO; CO2; O2 depletion; VOCs; Tenax-TA; SPME; process settings; storage temperature; storage time;

    Sammanfattning : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. LÄS MER

  3. 2. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties

    Författare :Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Sammanfattning : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. LÄS MER

  4. 3. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents

    Författare :Pierre Oesterle; Stina Jansson; Jerker Fick; Ulrika Rova; Capucine Dupont; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Activated biochars; HTC; regeneration; analytical chemistry; adsorption; degradation; nontarget analysis; wastewater; circular economy; emerging contaminants; surface chemistry; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap; Pharmaceutics; galenisk farmaci; analytisk materialfysik; analytical material physics; Analytical Pharmaceutical Chemistry; analytisk farmaceutisk kemi;

    Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER

  5. 4. Bio-coal for the sustainable industry : A scientific approach to optimizing production, storage, and usages

    Författare :Aekjuthon Phounglamcheik; Kentaro Umeki; Markus Broström; Capucine Dupont; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Bio-coal produced from biomass is a promising material to replace fossil coal in order to achieve net-zero greenhouse gas emission from the industrial sector. Bio-coal with quality comparable to that of fossil coal can be produced by high-temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low bio-coal yield at high pyrolysis temperatures.
