NO and SO 2 removal by dielectric barrier discharge-photocatalyst (DBD-P) hybrid process was examined for various conditions of process variables. Alumina beads were coated with TiO 2 thin film by a rotating cylindrical PCVD reactor and they were packed inside the cylindrical reactor. The NO and SO 2 removal efficiencies can be enhanced by using a combination of dielectric barrier discharge and photodegradation by TiO 2. The stronger the applied voltage is, the higher the pulse frequency is, or the longer the gas residence time is, the higher the NO and SO 2 removal efficiencies become. By applying additional photocatalytic effect, NO removal efficiency increased more significantly than SO 2 removal efficiency, because SO 2 removal efficiency was already high by dielectric barrier discharge only. In this study, we found that the alumina beads coated with TiO 2 thin film by a rotating cylindrical PCVD reactor could be used effectively to remove NO and SO 2 by DBD-P hybrid process.
