Catalytic oxidation of NO to NO2 on activated carbon

Catalytic oxidation of NO to NO2 over activated carbons PAN-ACF, pitch-ACF and coconut-AC at room temperature (30°C) were studied to develop a method based on oxidative removal of NO from flue gases. For a dry gas, under the conditions of a gas space flow rate 1500 h−1 in the presence of oxygen of 2–20% in volume concentration, the activated coconut carbon with a surface area 1200 m2/g converted about 81–94% of NO with increasing oxygen concentration, the pitch based activated carbon fiber with a surface area 1000 m2/g about 44–75%, and the polyacrylonitriale-based activated carbon fiber with a surface area 1810 m2/g about 25–68%. The order of activity of the activated carbons was PAN-ACF
