ABSTRACT:
Devolatilizable fine-grained material which contains hydrocarbons is devolatilized by means of fine-grained solids which have been heated to temperatures of about 500.degree. to 1000.degree. C. The devolatilizable fine-grained material is mixed with the heated solids and is thus heated to temperatures of about 400.degree. to 900.degree. C. The mixture is passed through a dwell zone, and gaseous and vaporous devolatilization products are withdrawn and cooled.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 devolatilizable fine-grained material is introduced into said stream in order to be admixed thereto. The heated solids and the devolatilizable fine-grained material can be mixed in a weight ratio of 3:1 to 12:1. The stream of trickling heated soids can be deflected at least in part.
