초록

Ceramic foams prepared from silica -day were coated with T1O₂ and V₂O5 catalysts for selective catalytic reduction of NOx with NH₃, The effects of V₂O5 loading, reaction temperature, space velocity, and oxygen content on NOx reduction with NH₃ were mainly investigated Also, the NOx reduction characteristics of V₂O5 and V₂O5 -T1O₂ filters were compared when sulfur dioxide exists From the results, the optimal NOx reduction with the maximum reduction efficiency of 91 % could be performed under the condition with V₂O5 loading 6 .0 wt %, reaction temperature 35.0°C, space velocity 6,000h-¹, and oxygen content 5% And, the V₂O5-T1O2 filters have shown higher NOx reduction efficiency and acid resistance against sulfur dioxide than the V₂O5 filters
