3. 2. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion

   Författare :Daniel Fleig; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO3; acid dew-point; coal combustion; oxy-fuel; sulfur; flue gas recycle; corrosion; Carbon capture and storage; H2SO4; SO2;

   Sammanfattning : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. LÄS MER

4. 3. Studies of NOx Storage Catalysts - Preparation, Characterization, Sulfur Deactivation and Micro Kinetic Modelling

   Författare :JAZAER DAWODY; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic modelling; metal oxide additives; NO oxidation; Zeta potential; FTIR; SO2 oxidation; Al2O3; NOx storage and reduction catalysts; TEM; BaCO3; SEM; Pt precursors; sulfur deactivation;

   Sammanfattning : For the protection of the global environment, it is essential to decrease the emissions of CO2 which is a green house gas. Lean-burn and diesel engines offer relatively low CO2 emissions and good fuel economy. LÄS MER

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

   Författare :Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Oxygen Vacancy Chemistry in Ceria

   Författare :Jolla Kullgren; Kersti Hermansson; Shluger Alex; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ceria; Density Functional Theory; Oxygen storage; Nano crystals; Sulfur poisoning; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. LÄS MER
