A method of preparing an adsorbent which contains a medium, which medium may comprise water. The medium is removed from the adsorbent by a hot regeneration gas, and the adsorbent is then cooled, wherein heat recovered during said cooling is used to heat the regeneration gas in a heat accumulator/exchanger. In order to improve the dewpoint characteristics of the dried gas, the adsorbent is passed successively through the following zones: an adsorption zone in which the adsorbent adsorbs the given medium; a regeneration zone in which the regeneration gas is passed through the adsorbent; and a cooling zone in which heat is withdrawn from the adsorbent, to be transferred to the heat accumulator/exchanger. An apparatus suitable for carrying out the described method is also described.
