  1. 11. Nanotemplated High-Temperature Materials for Catalytic Combustion

    Författare :Erik Elm Svensson; Sven Järås; Magali Boutonnet; James J. Spivey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon templating; Catalytic combustion; Ceria; Gas turbine; Hexaaluminate; Magnesia; Methane; Microemulsion; Perovskite; Chemical engineering; Kemiteknik;

    Sammanfattning : Catalytic combustion is a promising technology for heat and power applications, especially gas turbines. By using catalytic combustion ultra low emissions of nitrogen oxides (NOX), carbon monoxide (CO) and unburned hydrocarbons (UHC) can be reached simultaneously, which is very difficult with conventional combustion technologies.

  3. 12. Development of catalysts for natural gas-fired gas turbine combustors

    Författare :Sara Eriksson; Magali Boutonnet; Pio Forzatti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AZEP; catalytic combustion; CPO; methane oxidation; palladium; rhodium; support effect; Chemical engineering; Kemiteknik;

    Sammanfattning : Due to continuously stricter regulations regarding emissions from power generation processes, further development of existing gas turbine combustors is essential. A promising alternative to conventional flame combustion in gas turbines is catalytic combustion, which can result in ultralow emission levels of NOx, CO and unburned hydrocarbons. LÄS MER

  5. 14. System studies of MCFC power plants

    Författare :Benny Fillman; Pehr Björnbom; Professor Mats Westermark; Gábor Merényi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; fuel cell systems; system studies; process simulation; molten carbonate; Brennstoffzellen; Brennstoffzellensystem; Systemanalyse; Prozeßsimulation; Bränsleceller; bränslecellssystem; systemstudier; processimulering; smältkarbonatbränslecell; Chemical engineering; Kemiteknik;

    Sammanfattning : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. LÄS MER

  7. 15. Environmentally friendly utilization of biomass

    Författare :Alejandro Grimm; Emilia Björkbom; Mats Westermark; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Sammanfattning : The thesis deals with various ways of utilization of biomass. Chapter 1 compares three biomass types: birch wood Betula sp., marine brown alga Fucus vesiculosus, and terrestrial moss Pleurozium schreberi, as precursors for preparation of biosorbents for removal of copper ions from diluted water solutions. Small sample doses (0. LÄS MER
