Abstract :
New atmospheric pollution control process for the treatment and reduction of NOx gas from industrial and vehicle exhausted gases was proposed with intensive use of nucleation process of foreign aerosols and Ni catalyst for the enhancement of NOx oxidation. The technique, which is called as the aerosol driven De-NOx process, is based on the reduction of such trace gases by condensational growth following heterogeneous nucleation of NH3, NO, NO2, H2O and NH4NO3 vapors onto foreign nuclei adding in the reacting system. This technique should be considered as the super process of usual non-thermal plasma technique with ammonium radical shower at high temperature. The efficiency of this De-NOx process associated by the aerosol driven and chemical reaction of NOx with ammonium radical shower was 13.7g/kWh and improved remarkable comparing with usual NTPT (6.7g/kWh) especially at 100degC. It is considered that the particulate process via nucleation, condensation and particle surface reaction was promoted and enhanced by aerosol-drive process.
