Catalyst for desulfurizing and denitrating at the same time and its application method

A desulfurizing-denitrating catalyst contains cellular activated carbon (90-99.9 wt.%) and V2O5. It is applied through putting it on supporter in fixed-bed reactor and reacting on fume at 150-250 deg.C and 500-5000/hr of space speed. Its advantage is high transform rate of 80% for SO2 and 50-100% for NO.
