Gas purification method |
| abstract |
Provided is a gas purification method in which the amount of adsorbent is reduced, an adsorption column can be considerably miniaturized, the amount of regeneration gas can be reduced and the running cost can be reduced in cases where carbon dioxide or water which is an impurity contained in a gas to be purified is adsorptively removed; and in which a gas to be purified which contains carbon dioxide having a partial pressure of 35 Pa or lower as impurities is brought into contact with an adsorbent whose heat-regeneration temperature is set to from 160° C. to 240° C. composed of a faujasite type zeolite whose cation is sodium to adsorptively remove the carbon dioxide. Also provided is a gas purification method in which a gas to be purified is brought into contact with an adsorbent which is subjected to an initial activation at 300° C. or higher and composed of a faujasite type zeolite whose cation is lithium to adsorptively remove the residual carbon dioxide and a heat-regeneration is performed at 240° C. or lower. |
