  1. 1. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas

    Författare :Fredrik Lind; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; Moisture measurements; Biomass combustion; Oxygen carriers; Ilmenite; Catalytic gas cleaning; CFB; Tar cleaning;

    Sammanfattning : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. LÄS MER

  3. 2. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes  in power plants

    Författare :Zhafira Darmastuti; Anita Lloyd Lloyd Spetz; Lars Ojamäe; Mike Andersson; Niclas Lindqvist; Mikael Larsson; Jaco Visser; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.

  4. 3. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Författare :Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Nyckelord :Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Sammanfattning : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. LÄS MER

  5. 4. Mercury and dioxins in a MercOx-scrubber

    Författare :Carl-Johan Löthgren; Bert Allard; Bert van Bavel; Sven Andersson; Ivars Neretnieks; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waste incineration; flue gas cleaning; PCDD PCDF; PBDD PBDF; wet scrubber; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : The removal of mercury and the absorption of dioxins in an acid wet scrubber have been studied in industrial scale. Hydrogen peroxide is added as an oxidizing agent to the scrubber liquid with the purpose to remove SO2 and enhance the removal of mercury. LÄS MER

  7. 5. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration

    Författare :Duong Ngoc Chau Phan; Stellan Marklund; Bogdan Dlugogorski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Incinerations; dioxins; PCDD Fs; PCBs; PCNs; flue gas; fly ash; sampling; particle characterization; XPS; XRD; SEM EDX; formation; chlorination; PCA; OPLS; OPLS-DA;

    Sammanfattning : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. LÄS MER
