摘要： A nitrogen-containing molecular sieving carbon which contains at least 0.1 weight % nitrogen bonded to constituent carbon of the activated carbon. It exhibits improved ability to remove nitrogen oxides compared with the conventional adsorption methods using commercially available activated carbons or other absorbents. Also an economically advantageous system for removing nitrogen oxides is provided which needs no reducing agent such as ammonia, no oxidizing agent such as ozone, or no electrical and physical energy such as electron rays or ultraviolet light in its operation, needs no expensive catalysts, and can be semipermanently operated with regular changes of the relatively low-priced activated carbon.
