ABSTRACT TO THE DISPLOSURE : Devolatilizable fine-grained material which contains hydrocarbons is devolatilized by means of fine-grained solids which have been heated to temperatures of about 500 to 1000°C. The devolatilizable fine-grained material (conduit 5) is mixed with the heated solids (from conduit la) and is thus heated to temperatures of about 400 to 900°C. The mixture is passed through a dwell zone (6), and gaseous and vaporous devolatili- zation products are withdrawn (conduit 8) and cooled. The heated solids are fed to the dwell zone as a loosened stream in a trickling and/or agitated state of motion, and the devola- tilizable fine-grained material is introduced into said stream in order to be admixed thereto. The heated solids and the de- volatilizable fine-grained material can be mixed in a weight ratio of 3:1 to 12:1. The stream of trickling heated solids can be deflected at least in part.
