Abstract :
The removal performance of dilute trichloroethylene (100-1,000 ppm TCE) contaminated in air by using nonthermal plasma processing combined with a catalyst is newly studied. Two catalysts are tested by comparing three different types of reactors. Catalysts tested were a few mm disc-like Cu-ZSM-5 (zeolite) and vanadium oxide pellets of a few mm (V 2O5/TiO2). In order to separate TCE removals by the TCE absorption effect on the catalyst and the decomposition by the plasma processing with catalyst, TCE removal rate change with time was investigated. The relaxation time of absorption was from 6 to 80 minutes, which may be dependent on geometry and surface of the catalyst. Decomposition energy efficiency was estimated to realize the practical TCE remover
