1P-466 Odorous and Hazardous Gases Removal Property of Granule-type Filter Media containing Copper-Manganese Oxide Catalyst = 1P-466 Odorous and Hazardous Gases Removal Property of Granule-type Filter Media containing Copper-Manganese Oxide Catalyst

다국어 초록 (Multilingual Abstract)

The cylindrical-type porous pellets containing copper-manganese oxide catalyst were prepared by roller-dice extrusion method. The physical properties such as pellet density, hardness, and porous parameters along with the gas removal performance were investigated depending upon the various process parameters such as silica fillers, binders, additives, and processing parameters, etc. It was found that the newly prepared oxide catalyst-loaded pellet type granules exhibited excellent mechanical and physico-chemical properties; high pellet hardness(＞4.0 kg/㎠), very low packing density (＜0.4 g/㎤), large pore volume (＞0.80 ㎤/g) and specific surface area (＞ 200 ㎡/g), respectively. It was interesting that the CO removal efficiency showed no strong correlation with porous property. In particular, the filter media using active carbon exhibited very low CO removal efficiency even though the large specific surface.
