  1. 1. Metal-exchanged zeolites for NH3-SCR applications - Activity and Deactivation studies

    Author : Soran Shwan; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; modeling; NOX.; Hydrothermal; Chemical; Kinetic; Copper; Deactivation; Iron; Zeolite; Nitrogen oxides; NH3; Ammonia; Catalyst; NSR; Emissions; Poisoning; Ageing; NH3-SCR;

    Abstract : Emissions of nitrogen oxides (NOX) formed during the burning process in internal combustion engines is a major contributor to global air pollutions. One effective way to reduce NOX in lean environments, i.e. oxygen excess is selective catalytic reduction with ammonia (NH3-SCR). READ MORE

  2. 2. Kinetic modeling of autothermal reforming of heptane for a fuel cell - auxiliary power unit

    Author : Mattias Modén; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heptane; Keywords: Steam reforming; Kinetic modeling; Oxidation; Autothermal reforming; FC-APU;

    Abstract : AbstractThe transport sector contributes significantly to the increasing amounts of air pollution. The pollution from idling heavy duty vehicles can be reduced by using a fuel cell auxiliary power unit (FC-APU) that supplies the vehicle with electricity. This licentiate thesis deals with production of hydrogen, which feeds the fuel cell. READ MORE

  3. 3. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Author : Björn Lundberg; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Abstract : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. READ MORE

  4. 4. Biomass gasification in fluidized bed gasifiers Modeling and simulation

    University dissertation from Västerås : Mälardalen University

    Author : Guilnaz Mirmoshtaghi; Mälardalens högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

  5. 5. Selective Catalytic Reduction of NOx with NH3 - Kinetic Modeling and Experimental Studies using Zeolite Based Catalysts

    University dissertation from Västerås : Mälardalen University

    Author : Hanna Maria Sjövall; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective catalytic reduction; SCR; NO reduction; Ammonia; Fe-zeolite; DRIFT; Cu-ZSM-5; Zeolite; Nitrogen oxide; Kinetic modeling;

    Abstract : Emissions from the combustion of fossil fuel contain several pollutants which can be converted over a catalyst to less harmful products. An efficient way to reduce nitrogen oxides in a lean environment is to apply selective catalytic reduction of these oxides with ammonia (NH3 SCR). READ MORE
