EXPERIMENTAL-STUDY ON OZONE SYNTHESIS VIA DIELECTRIC BARRIER DISCHARGES

The characteristics of ozone generation using a dielectric barrier dis charge reactor were investigated experimentally. Results indicate that ozone concentration increases with increasing applied voltage and gas residence time. In addition to applied voltage, ozone generation rate varies with reactor configuration as well. Optimum ozone generation r ates can be reached at the specific gas residence time for a given app lied voltage and gas composition. At the same applied voltage, the rea ctor with a single dielectric barrier results in a higher ozone genera tion rate in comparison with the reactor having double dielectric barr iers. Given a constant N-2/O-2 ratio in the feed gas, NOx concentratio n increases as applied voltage and gas residence time increase. Result s indicate that maximum NOx concentration is reached when the N-2/O-2 ratio of feed gas is 4.
