    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective oxidation; Czochralski; YMn4Al8; clathrate; heterogeneous catalysis; thermoelectricity; noble metals; mesoporous; phonon glass-electron crystal; figure-of-merit ZT ;

    Abstract : New materials have been researched for environmental applications as thermoelectrics and low-temperature oxidation catalysts. One of the main objectives of this thesis was to prepare and characterize new efficient thermoelectric materials (TM’s). READ MORE

  4. 7. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

    Author : Göran Olofsson; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

    Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

  5. 8. Studies of partial oxidation and combustion over heterogeneous catalysis by transient experiments
