Paper Title:
Removal of NO2 and SO2 Using Porous Media Made from Sewage Sludge
  Abstract

This study was carried out to investigate adsorption characteristics on NO2 and SO2 for two kinds of media, ie the carbonated media and its zeolite coated media with sewage sludge. Porous media was manufactured through processes of drying, extruding, forming, carbonation and washing. Zeolite was coated on the media, and then thermally treated. Test of NO2 and SO2 removal was peformed by detecting NO2 and SO2 concentration at inlet and outlet of the reactor continuously flowing the mixed gas. Zeolite coated media showed higher than carbonization media in removal efficiency of NO2 and SO2. Also, zeolite coated media took shorter time for achieving in 84% removal of SO2 than carbonated media. And, zeolite coated media showed that removal efficiency of NO2 and SO2 maintained high in early stage as well as time elapsing. It make possible the zeolite coated media remove SO2 and NO2 for long time. As a result, micro pore in zeolite could increase breakthrough time and adsorption capability, compared to macro pore in carbonated media. Zeolite coating on porous media would be effective on removal of SOx and NOx.
