  4. 2. Ash transformation during thermochemical conversion of agricultural biomass in entrained flow conditions

    Author : Samarthkumar Pachchigar; Marcus Öhman; Markus Broström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agricultural biomass; entrained flow conditions; combustion; ash transformation; Si recovery; P recovery; Energiteknik; Energy Engineering;

    Abstract : Agricultural biomass is considered a prospective renewable feedstock in the energy conversion units. Despite its widespread availability, agricultural biomass is often underutilized in the thermochemical processes due to its high ash content. READ MORE

  5. 3. Leaching and Transformation of Flame Retardants and Plasticizers under Simulated Landfill Conditions

    Author : Maritha Hörsing; Bo H. Svensson; Susanne Jonsson; Anna Karlsson; Cynthia de Wit; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DEHP; BBP; tetrabromobisphenol A; TBBPA; TBBPA-DAE; TBBPA-DBPE; TBBPA-DHEE; Proban; Pyrovatex; Melamine; Environmental chemistry; Miljökemi;

    Abstract : Many products used in our everyday life contain chemicals added to give them specific properties. Flame retardants (FRs) are added to prevent or retard fires in textiles, plastics etc., while plasticizers are supplied to make plastics more flexible. READ MORE

  6. 4. Experimental studies of ash transformation processes in thermochemical conversion of P-rich biomass and sludge

    Author : Gustav Häggström; Marcus Öhman; Rainer Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ash transformation; phosphorus recovery; sewage sludge; chicken manure; Energy Engineering; Energiteknik;

    Abstract : The efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus present in manure and sewage sludge. READ MORE

  7. 5. In-situ phase studies of the Zr-H system

    Author : Tuerdi Maimaitiyili; Malmö högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium hydride; synchrotron X-ray diffraction; neutron diffraction; phase transformation; in-situ hydrogen charging; hydrogen related degradation; in situ phase transformation; hydrogen embrittlement; hydrogen charging; zirconium hydride; γ-ZrH; synchrotron X-ray diffraction; neutron diffraction; hydrogen induced degradation;

    Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. READ MORE
