| Research Abstract |
This project was carried out from April 2000, to March 2004 supported by the "Grand-in-Aid for Scientific Research (A) from JSPS. Main target of this project is development of the atmospheric pressure non thermal plasma technology as the removing the gaseous contaminants in the air or in the combustion flue gas. For flue gas cleaning, De-NOx process was investigated and for clean air, removal of 100 -1,000 ppm VOCs (volatile organic compounds) in air is another aim of this project. Geometrical effect of the reactor, drive power supply were optimized. A bolt type barrier discharge reactor was the best among the tested reactors. To enhance the removal energy efficiency, some catalysts were examined, such as titanium oxide, vanadium oxide, tungsten oxide, Manganese oxide can reduce ozone and improve the decomposition efficiency of dilute TCE (trichloroethylene). When the TCE contaminated air is mixed with the plasma processed clean air, TCE can be decomposed, which was named as Indirect Process. Normal process, the TCE contaminated air passes through the plasma reactor, was, then, named as the Direct Process. At best case, TCE removal efficiency is more than 95 % where specific discharge energy was 30 J/L. As the diagnosis process of that plasma, LIF technologies for OH radical, NO, NO^*, oxygen molecule, atomic oxygen radicals were established in spatial and time divisions. Other optical methods of Laser-Schlieren Method is developed for density measurement and the ozone distribution could be observed by using laser-Beam Absorption method of UV light. Those diagnosis technologies built up during this project.
