Abstract
This study attempted to decompose typical odorous VOCs including toluene, isopropyl alcohol, benzene and acetone using a dielectric barrier discharge plasma in a pilot experiment scale up to 60 m3/min. It utilized oxygen ions(205,000 ions/cm3) and various radicals formed by a plasma generator. Although ozone as a byproduct(approximately 300 ppb) contributes to destroying organic compounds in their gas phase, the residual release could be captured by post manganese filters showing a maximum 30% removal. The present process was more effective for acetone, which is composed of relatively simple molecules, with a 56% decomposition rate. Whilst toluene, benzene and isopropyl alcohol were shown to have of rates of 19%, 37% and 36% respectively.
