Kinetics of the biofuels-assisted SCR of NOx over Ag/alumina-coated microchannels

Catalytically active microchannels containing 1.5 wt.% Ag/alumina were used for studying the kinetics of the hydrocarbon-assisted selective catalytic reduction of NOx. Hexadecane, a model component for second-generation biodiesels, was used as a reducing agent. Steady-state data from the microreactor was used to develop a detailed kinetic model. The kinetic parameters were estimated through numerical data fitting, with plug flow model for the microchannels. The model explained fairly well the experimental data.
