  1. 1. The influence of SO2 on the high temperature corrosion of Fe and Fe-Cr alloys

    Författare :Anders Järdnäs; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; H2O; high temperature corrosion; Fe-2.25Cr-1Mo steel; SO2; 304L; oxidation;

    Sammanfattning : Sulfur dioxide is an important pollutant in combustion gases and plays a major role in the high temperature corrosion of many metals and alloys. This work investigates the influence of small amounts of SO2 on the high temperature corrosion of iron, chromium and several Fe-Cr alloys. LÄS MER

  5. 4. Sulfur Capture and Oxidation of Calcium Sulfide in PFBC

    Författare :Kuanrong Qiu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; model; pressure; sulfur; PFBC; CaS; limestone; CaSO4; PTGA; regeneration;

    Sammanfattning : Sorbents such as limestone are successfully used for removal of SO2 during pressurized fluidized bed combustion (PFBC) processes. However, there still remains a strong incentive to reduce the consumption of such sorbents. LÄS MER

  7. 5. 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
