In regenerating an adsorbent by eliminating water and an adsorbed matter which are contained therein, the adsorbent is indirectly heated while descending within a drying furnace and is indirectly heated while ascending within a regenerating furnace in order to prevent the adsorbent from scattering due to water vapor and the adsorbed gas separated by the heating of the adsorbent and to prevent the adsorbent from burning itself due to heat.
