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

    Author : JAZAER DAWODY; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : To a large extent, organic building blocks are today obtained from petroleum-based products. From an environmental point of view, biomass-derived compounds are more sustainable alternatives to such oil-derived molecules. The 12 principles of green chemistry describe how chemical processes can be improved in terms of sustainability. READ MORE
