  1. 21. The Release, Distribution, and Implications of Alkalis in Chemical Looping Combustion of Biomass

    Författare :Ivan Gogolev; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical looping combustion; carbon capture; alkali release; biomass;

    Sammanfattning : Chemical looping combustion (CLC) of biomass is a promising technology for power generation with a potential net negative CO2 footprint. Like other fluidized bed biomass conversion technologies, biomass CLC may be susceptible to alkali-induced  agglomeration, fouling, and corrosion. LÄS MER

  3. 22. Application of fuel design to mitigate ash-related problems during combustion of biomass

    Författare :Anders Rebbling; Christoffer Boman; Dan Boström; Marcus Öhman; Nils Skoglund; Sonja Enestam; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical energy conversion; biomass; combustion; ash chemistry; fuel design; ash transformation reactions; renewable energy;

    Sammanfattning : The energy supply of today is, through the use of fossil energy carriers,contributing to increased net emissions of greenhouse gases. This hasseveral negative effects on our environment and our climate. In order toreduce the impact of this, and possibly to reverse some of the effects, allrenewable energy sources must be used.

  4. 23. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach

    Författare :Farzad Moradian; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized-bed; combustion; gasification; waste-derived fuels; biomass; ash-related problems; deposit; fouling; slagging; bed agglomeration; thermodynamic equilibrium modeling;

    Sammanfattning : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. LÄS MER

  5. 24. Investigation of thermal biomass gasification for sustainable small scale rural electricity generation in Uganda

    Författare :Joseph Olwa; Torsten Fransson; KTH; []
    Nyckelord :Tar; Gasification; Biomass; SRA - Energy; SRA - Energi;

    Sammanfattning : With the increasing need for renewable energy technologies in the world, biomass fuel transformation technology is growing towards meeting that need, among others. Challenges remain certain and new innovations are being tested in bid to overcome them with the application of biomass as energy source. LÄS MER

  7. 25. Process Integration Opportunities for Synthetic Natural Gas (SNG) Production by Thermal Gasification of Biomass

    Författare :Stefan Heyne; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; synthetic natural gas; energy systems; process integration; renewable energy;

    Sammanfattning : Synthetic natural gas (SNG) from gasified biomass is one promising option to produce renewable transport fuels. This thesis presents a process integration study investigating thermal gasification of biomass for the production of SNG and identifies critical conversion steps for the overall process performance.
