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

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

    Abstract : 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. READ MORE

  4. 2. Particulate Debris Spreading and Coolability

    Author : Simone Basso; Pavel Kudinov; Florian Fichot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-leveling; debris bed; spreading; coolability; severe accident; probabilistic framework; Monte Carlo; uncertainty; sensitivity; Fysik; Physics;

    Abstract : In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. READ MORE

  5. 3. On the optimization of the fluidized bed particulate coating process

    Author : Savini Maronga; KTH; []
    Keywords : ;

    Abstract : Different aspects that influence the fluidked bedparticulate coating process have been investigated. An easy touse procedure for creating temperature and humidity profilesfor the gas inside the bed was developed. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Treatment conditions for the removal of contaminants from road runoff

    Author : Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

    Abstract : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. READ MORE
