  1. 1. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER

  3. 2. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Författare :Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Nyckelord :biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. LÄS MER

  4. 3. High temperature aerosol formation and emission minimisation during combustion of wood pellets

    Författare :Henrik Wiinikka; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Combustion of solid biomass under fixed bed conditions is a common technique to generate heat and power in both small and large scale grate furnaces (domestic boilers, stoves, district heating plants). From both an environmental and economical perspective, one of the most interesting alternatives to replace oil and electricity for heating of family houses and apartments in Sweden is wood pellets made of stem wood sawdust from pine and spruce.

  5. 4. Benzene-char conversion and particle-vapor characterization in biomass gasification

    Författare :Mario Morgalla; Michael Strand; Leteng Lin; Henrik Wiinikka; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; fluidized bed; particulate matter; aerosol; char; tars; benzene conversion.; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER

  7. 5. Char conversion kinetics and aerosol characterization in biomass gasification

    Författare :Leteng Lin; Michael Strand; Alberto Gómez-Barea; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; fluidized bed; char; kinetics; aerosol; APS; TEOM; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. LÄS MER
