Removal of Nitric Oxide over Saskatchewan Lignite and its Derivatives

Abstract

Adsorption of nitric oxide was studied over reduced and unreduced Fe, Cu, Co and Ni impregnated activated carbons (AC) in a microreactor system in the presence and absence of oxygen. In the absence of oxygen reduced Fe-AC showed an NO removal efficiency of 58% which was higher than that of virgin activated carbon by a factor of 2.5. The removal efficiency of Cu-AC with and without oxygen was in the range of 44-46%.
