Abstract
AbstractDilute trichloroethylene (TCE) decomposition by the non-thermal plasma processing is investigated concerning with the enhancement of the removal-energy efficiency by use of the catalyst. Tested catalysts are zeolite, titania, vanadium oxide and tungsten oxide, which are inserted into the plasma region as pellets of a few mm spheres or discs. As the zeolite adsorbs too much TCE during a long period, the enhancing effect on the removal energy efficiency by the zeolite is not yet clear, but other catalysts can surely reduce the necessary energy to decompose TCE. As there are still too many parameters affecting the removal performance, the best catalyst, as enhancing the plasma processing, and that operating conditions will be analyzed in future.
