Abstract

NaOH solution was used as the modifier for fly-ash. Through orthogonal experiments, a suitable operating condition for the modification was selected. The modified fly-ash was mixed with slaked lime and adhesive to make a kind of nitric oxides adsorbent. The results of the dynamic state experiments show that the adsorbent named B made from the modified fly-ash performs better in NO and NO₂ adsorption than the adsorbent named A, which was made from raw fly-ash. In the specific condition in this paper, the NO_x, adsorption quantity of B was 5. 36% higher than that of A. The adsorption mechanism of this absorbent can be attributed to physical adsorption, chemical adsorption and absorption.
