<p>An adsorbent for nitrogen separation comprising molecular-sieve carbon prepared by the halogenation, dehalogenation followed by micropore adjustment of carbonized coal. The adsorbent can increase the quantity of nitrogen generated per unit quantity thereof, enhance the nitrogen yield, and reduce the nitrogen production cost. An adsorbent for carbon dioxide or methane comprising activated carbon prepared by the halogenation, dehalogenation followed by activation of carbonized coal can adsorb the gas in an increased quantity.</p> |
