Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for the rise of the so-called smog and there are particularly dangerous to living organisms and to climate. NO is easily oxidized in air into nitrogen dioxide (within 30 sec. 92% of NO into NO2 passes). This study describes the method used in industry, reduction of nitrogen oxides using activated carbon bed. The reactor consists of a series of tubes packed in each one the reaction NO + C -> CO + 1/2 N2. The reaction followed by purification of air through the NO reduction. To obtain the design results, you can use the ODE / PDE interfaces. The use of the CFD Module allowed to choose the optimal length of the reactor and to find the weak points of the model.
