Emission control

The reduction of emissions of local pollutants (NOX, CO, aldehydes, particulate matter, etc.) arising from combustion engines, industrial plants, and residential sources is achieved by advanced exhaust-gas after-treatment
systems. A special focus is given to the reduction of NOemissions by selective catalytic reduction (SCR), the
elimination of toxic pollutants such as formaldehyde and HCN, and better reaction engineering strategies for the removal of the green-house gases such as CH4 and N2O. Advanced capillary techniques and laser spectroscopy
such as PLIF supports the understanding of the catalytic devices for cleaning exhaust gases. Slip of the
greenhouse gases methane and N«O from modern engines fueled by natural gas and hydrogen, resp., are reduced by the application of advanced catalysts and optimised operating conditions.
