Improvement of DE-NOX efficiency by NTPT and aerosol driven process associated with oxidation by NI catalyst

New atmospheric pollution control process for the treatment and reduction of NO_x 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 NO_x oxidation. The technique, which is called as the aerosol driven De-NO_x 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.
