Reduction of NO at Very Low Concentration in Air with NH3 at Room Temperature over a Series of Calcined Pitch Based Active Carbon Fibers
1995
Catalytic activities of a series of pitch based active carbon fibers (ACFs) were examined for the reduction of NO (10 ppm) with NH3 (20 ppm) at 293 K. A particular ACF of 840 m2 g−1 surface area exhibited the excellent activities after the calcination at 1123 K, providing conversions of 75 and 47 % in dry and wet (80 % relative humidity) air, respectively, at W/F of 5 × 10−3 g min ml−1. The ACF of the largest surface did not show the largest activity.
