Abstract
A process and an apparatus for desorption, e.g. desorbing a solvent, from a bedding (4) of adsorbent material (14), e.g. activated carbon, by means of a hot gas flow, e.g. air, so that a wave of concentration induces, which goes through the bedding by means of the hot gas flow. The invention is characterized in that the concentration wave is controlled to reach the gas flow outlet of the bedding surface successively.
