<p>PURPOSE:To contrive the recovery of a difficultly adsorbable gas with a good degree of efficiency by providing a porous resistance plate perpendicularly to a gaseous stream on an adsorbent bed of an adsorptive separating tower filled with adsorbent. CONSTITUTION:A mixed gas (e.g. air) is separated into a difficultly adsorbable gas (e.g. oxygen) and an easily adsorbable gas (e.g. nitrogen) by pressure swing process using an adsorbent (e.g. zeolite) for effecting a selective adsorption of the gas of a specific component. A porous resistance plate 13 is provided perpendicularly to a gaseous stream on an adsorbent bed 11 of an disruptive separating tower 10 filled with the adsorbent. This reduces the amount of the easily adsorbable gas being carried off with the difficultly adsorbable gas in the process of recovering the difficultly adsorbable gas, which, therefore, can be efficiently recovered as a whole.</p> |
