PROBLEM TO BE SOLVED: To provide a catalyst for removing NO2 which can attain the improvement in a denitration capacity in a specified temperature range when the composition ratio of NOx in exhaust gas is NO2 -rich and a method for removing NO2 using the catalyst. SOLUTION: In the catalyst for removing NO2 , the oxide of at least one kind of manganese, copper, and chromium is carried on a titanium oxide carrier. In a method for removing NO2 , by using the catalyst, nitrogen dioxide in exhaust gas is converted into N2 by selective catalytic reduction by a reducing agent of NH3 at 150-300 deg.C. |
