Dynamic NO adsorption characteristics of iron-treated activated carbon fibers

Abstract

The breakthrough curve for NO adsorption on the activated carbon fibers treated in iron salt solutions was determined. They can adsorb much more NO than granular activated carbon by a factor of more than 10 from a flowing 300 ppm NO-N 2 mixed gas at 100°C and 20 ml min −1; the most effective one of the iron-treated carbon fibers of 0.2 g is able to reduce the NO concentration from 300 ppm to 30 ppm. These adsorbents can adsorb the same amount of NO from even a 300 ppm NO-500 ppm SO 2-10% CO 2-10% H 2O-1% O 2-N 2 mixed gas.
