Abstract：The experiment system of regenerating ceramic foam adsorbate（CFA） was established based on NTP injection. The active substance of CFA produced by the NTP reactor was investigated at different temperatures of the control area and O2 flow rates. The experimental results indicate that for constant O2 flow rate, the regeneration time of CFA is decreased at first and then increased with the increase of the control area temperature to obtain optimum temperature of 225 ℃. For invariable temperature of the control area, the regeneration time of CFA is decreased at first and then increased with the increase of O2 flow rate to give optimum flow of 4 L?min-1. The NTP technology can effectively remove PM and regenerate CFA at low temperature of the control area. The results provide the basis for regenerating diesel particulate filter based on indirect nonthermal plasma system.
