Characteristics of corona discharge generated in a honeycomb catalyst for air pollution control |
| 초록 |
A method based on a corona discharge produced by high voltage alternating current (AC) and direct current (DC) over a Pd/γAl2O3 catalyst supported on a honeycomb structure was developed to control air pollution. The characteristics of the AC and DC corona discharge generated inside the honeycomb catalyst were investigated by varying the humidity, gas hourly space velocity (GHSV), and temperature. The results showed that the AC discharge is strongly affected by the humidity, GHSV, and temperature whereas the effect of these parameters on the DC discharge is negligible. The average power and current for the DC plasma were typically much higher than for the AC plasma at the same applied voltage. The VOC removal in the DC honeycomb catalyst discharge is, therefore, higher compared with that in the AC honeycomb catalyst discharge. These new results can open opportunities for wide applications of DC corona discharge combined with honeycomb catalysts for VOC treatment in real-time. |
