Abstract

A process for thermal regeneration of charged activated coke or activated carbon granulate, in which the granulate is preheated in a preheating zone, and is then heated in a heating zone of a traveling bed by direct contact with a heated stream in the form of a partial stream of desorption gas expelled from the granulate. The granulate is then cooled in a cooling zone immediately after leaving the heating zone. The preheating and cooling procedures are carried out by using a heat exchange medium which is separate from the heated stream in the heating zone.
