The Combination of Non-Thermal Plasma and BaO catalyst for NO_x Storage-Reduction Process

摘要

A novel plasma-reduction process for deNO_x has been suggested. In this NO_x Storage-Reduction process, 80% of NO (initial concentration of 210ppm) was oxidized to NO_2 by the pulsed plasma with the specific input energy of 45J/L. NO_x storage to the alkaline-earth metals was confirmed. The mechanism of the NO_x storage and the reduction process was investigated using XRD and ion-chromatograpy. The reduction of absorbed NOx by exposing to the plasma was investigated in this research.
