  1. 1. 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

  3. 2. 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

  4. 3. 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

  5. 4. Exploration of bacteria associated with Anopheles mosquitoes around the world : For the prevention of transmission of malaria

    Författare :Louise K. J. Nilsson; Olle Terenius; Staffan Svärd; Sebastian Håkansson; Michael Strand; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbiota; microbiome; vector-borne disease; 16S rRNA gene; amplicon sequencing; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. LÄS MER

  7. 5. Particle emissions from residential wood and biodiesel combustion

    Författare :Robin Nyström; Christoffer Boman; Dan Boström; Markus Broström; Michael Strand; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Combustion; biomass; wood; biodiesel; particulate matter; emissions; aerosols; physicochemical properties; size distribution; PAH;

    Sammanfattning : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. LÄS MER
