Document Type and Number:
Japanese Patent JP3072129
Kind Code:
B2
Abstract:
Chlorine gas is concentrated by adsorbing a dilute chlorine gas onto an adsorbent and discharging it as a higher concentrated chlorine gas. In the method (i) the chlorine-contg. gas is introduced to the adsorbing tower which is filled with adsorbents (1). (ii) the pressure of the system is reduced and the gas is discharged. The desorbed gas has a higher concentration of chlorine. In this method the adsorbent can be recoverd automatically in the second step (ii). The adsorbent (I) is pref. a zeolite, a non-zeolite porous acidic oxide, or an activated carbon. The activated carbon is a molecule-filtering carbon.
