NO_X and SO_X Removal by Low Temperature Plasma-Photocatalysts Hybrid System

摘要

We analyzed the effects of several process variables on removal efficiencies of NO and SO_2 by the low temperature plasma process combined with photocatalysts. The cylinder-wire type, dielectric barrier discharge process for plasma generation was used. The photocatalysts were coated onto the glass beads by dip-coating method. As the voltage applied to the plasma reactor increases, or as the pulse frequency of applied voltage increases, the NO and SO_2 removal efficiencies also increase. As the initial NO concentration decreases, or as the residence time increases, the NO and SO_2 removal efficiencies increase.
