Abstract
Dielectric Barrier Discharge (DBD) plasma treatment is a promising and effective method for reduction of NOx in an oxygen rich environment. Dielectric material plays a very important role on the deNOx behaviour. Experiments showed that deNOx behaviour in a plate type reactor greatly changed depending on the properties of dielectric materials. In the case of quartz and silicone rubber, more than 99% of 400 ppm NO could be removed with 0.084-0.168 second of residence time. On the other hand, in the case of alumina, NOx increased to a relatively high level since the reaction between nitrogen and oxygen significantly proceeded.
