    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.

    摘要： A carbonaceous molecular sieve having micropores with diameters in the range of 4 to 6 Angstrom units and bromine as adsorbed on said carbonaceous molecular sieve is able to remove selectively low molecular weight organic gases such as ethylene, acetylene, methyl sulfide, acetaldehyde etc. from air and other gases containing the same with a reduced tendency toward deactivation with time, and is useful as a removing agent of low molecular weight organic gases.

    摘要： Nitrogen oxides contained in waste gases can be effectively removed from waste gases by a novel process which comprises contacting the waste gases with activated carbon in the presence of gaseous ammonia at a temperature between about 110.degree. C. and about 350.degree. C. to convert the nitrogen oxides to nitrogen. When waste gases containing sulfur oxides together with nitrogen oxides are subjected to this process, both the nitrogen oxides and the sulfur oxides can be simultaneously removed from the waste gases with a high efficiency. The effects of this process can be enhanced by employing a specific element-supporting activated carbon or an oxidized activated carbon.
