desorption. Technically speaking, the regeneration of adsorbate-laden activated carbon is achieved by exposing it to heat, e.g. in water vapour, hot gas or vacuum. The resultingrecovery of adsorbates plays an important role in solvent recovery processes, for example: If an adsorbent such as activated carbon is brought into contact with

A potential third bed is, after regeneration, dried, cooled and put on stand-by. Regeneration takes place by blowing steam into the bed so that the bed heats up and the VOC desorbs. This takes place at temperatures between 80 and 200 °C. After desorption, cooling air is blown into the bed so that it …
