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 increase quantity.
La présente invention concerne un adsorbant pour la séparation de l'azote, comprenant du carbone sur tamis moléculaire obtenu par halogénation et déshalogénation, suivies d'un ajustement au niveau des micropores du charbon carbonisé. Cet adsorbant permet d'accroître la quantité d'azote généré par unité, d'améliorer la production et d'en réduire les coûts. Elle concerne, en outre, un adsorbant pour dioxyde de carbone ou pour méthane comprenant du carbone activé obtenu par halogénation et déshalogénation, suivies d'une activation du charbon carbonisée, et pouvant, adsorber le gaz en plus grande quantité.
