Abstract: PURPOSE: Non-thermal plasma reactor employing dielectric barrier has been demonstrated to be an effective method for reducing such hazardous gases emissions as VOCs, PFCs and CFCs, and further recent researches have shown that non-thermal plasma reactor packing dielectric or ferroelectric between cathode electrode and anode electrode is more acceptable. In such dielectric-assisted non-thermal plasma reactors where high voltage alternative current is applied on exhaust gas passing through packed dielectric/ferroelectric for the reduction of hazardous emissions, transition metals such as Pt, Pd, Rh, Co, Ni and V are normally supported as catalysts on the dielectric/ferroelectric in the shapes of pellet, bead and honeycomb monolith. However, transition metals having superior electric conductivity have been reported it is quite probable that arc, interfering stable generation of non-thermal plasma, is likely to be produced when employed in electric-sensitive plasma reactor. In addition to abovementioned technical disadvantage, high cost is another concern over transition metal catalyst. Accordingly, it is required to develop cost-effective catalyst with no or reduced arc interference while sensitive to no-thermal plasma. CONSTITUTION: Researchers have found that rare earth-ion exchanged zeolite show superior effect on hazardous gas purification with no arc generations when applied to non-thermal plasma reactor employing dielectric/ferroelectric. In addition, a cocatalyst supported with transition metal species may be packed in non-thermal plasma reactor in order to enhance catalyst durability as well as reduce catalyst poisonings. Further, water or hydrogen peroxide, which generates oxidative hydroxyl radicals when applying high voltage alternative current, is allowable into the non-plasma reactor for the acceleration of hazardous compound oxidation.
