  2. 11. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Author : Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

    Author : Seyed Morteza Mousavi; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; particle model; bed model; CFD simulation; biomass; pyrolysis; ; combustion; gasification; potassium release; alkali;

    Abstract : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. READ MORE

  6. 14. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

    Author : Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals.
