PROBLEM TO BE SOLVED: To provide effectively and easily a flue gas denitrification process of being not inferior to other flue gas denitrification processes in respect of the denitrification efficiency and, therefore, carrying out the flue denitrification process of superior economic efficiency by using an active carbon catalyst for treating pores of desired diameter and providing them with repellency to demonstrate high activities. SOLUTION: A repellent substance having the contact angle with water of 90 deg. or more and not permeable into pores of 5 nm or smaller of active carbon is carried on active carbon powder having the average particle diameter in the range of 12-600 μm, preferably 15-400 μm, or more preferably 20-200 μm, and the adding percentage is in the range of 0.2-3.0 wt.%, more preferably 0.5-1.5 wt.%. The particles of fluororesin or a dispersion of the same are added into a mixture thus formed so that the adding percentage is in the range of 2-20 wt.%, preferably 5-15 wt.%, and the mixture is molded into the given shape. |
