PROBLEM TO BE SOLVED: To provide a denitrification catalyst for reducing and removing nitrogen oxides included in exhaust gas from burning waste in a low temperature range of 100-200 deg.C in the presence of ammonia. SOLUTION: The denitrification catalyst is provided, wherein active carbon supporting 5-15 wt.% of vanadium oxide or chromium oxide to which an iron oxide is added as an active component is used, wherein the iron oxide to which the iron oxide is added is that Cr2 O3 to which Fe2 O3 is added, and a weight ratio of the denitrification catalyst is Cr2 O3 : Fe2 O3 =9:1-1:1, and the active carbon of which acidity is increased by acid treatment has a specific surface area of 1,000 m<2> /g or more. |
