PURPOSE: To provide an adsorption separating device having high practical utility such as being capable of enough exhibiting catalytic ability or saving the amount of a catalyst.
CONSTITUTION: In a reaction column housing a catalyst provided together with a separating column 11 housing an adsorbent 12 and a heating mean 13 for heating the adsorbent 12, separation is carried out by adsorbing an effective component in a gaseous 1 with the absorbent 12. The effective component and a harmful component separated from the effective component are allowed to desorb from the adsorbent 12 by heating the adsorbent 12 with the heating mean 13, and then the harmful component being mixed with the effective component is removed selectively upon catalytic reaction by feeding the desorbed gas from the separating column 11 to the reaction column, except for the initial stage in the desorbing process of both the components and/or the latter period in which the harmful component is contained in a large amount.
