CARBONACEOUS ADSORBENT, PROCESS FOR PRODUCING THE SAME, AND METHOD AND APPARATUS FOR GAS SEPARATION

摘要

It is possible to increase the amount of nitrogen generated per unit of adsorbent, raise the nitrogen yield, and reduce the manufacturing cost for nitrogen by using, as an adsorbent for the separation of nitrogen, molecular sieving carbon obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and a pore adjustment treatment on a carbonized charcoal. By using activated carbon obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and an activation treatment on a carbonized charcoal, as an adsorbent for carbon dioxide and methane, it is possible to improve the amount adsorbed.
