  4. 2. Experimental Studies of NOx Catalysts; Storage, Reduction and Sulphur Deactivation

    Author : Annika Amberntsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barium oxide; NOx storage; platinum; rhodium; sulphur poisoning; NOx reduction;

    Abstract : The aim of this thesis work was to investigate how different gaseous compounds, present in an automotive exhaust from lean-tuned combustion, interact with so-called NOx storage catalysts containing Al2O3 as a support, BaO as the NOx storage compound and noble metals to provide oxidation and reduction functions. The investigations included model sample preparations, flow reactor studies with various gas mixtures and spectroscopic experiments (FTIR and XPS). READ MORE

  5. 3. Lipid Oxidation in Fillets of Herring (Clupea harengus) during Processing and Storage

    Author : Ingrid Undeland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipid oxidation; processing; storage; fish; Herring; Clupea harengus;

    Abstract : The influence of storage and processing on the development of lipid oxidation in herring fillets was investigated and related to their composition of lipids, catalysts and antioxidants. The progress of oxidation was monitored as antioxidant loss and as the development of primary, secondary and tertiary lipid oxidation products. READ MORE

  7. 5. RhPt and Ni based catalysts for fuel reforming in energy conversion

    Author : Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

    Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE
