ABSTRACT:
Carbon black having a high diphenylguanidine (DPG) value and a low pH value is produced in a reactor by separating the combustion gases into a plurality of streams by means of a perforate partition. This partition has a tubular portion or a conical portion which is surrounded by a plurality of through apertures at the downstream end. The hot combustion gases contact the make-hydrocarbon downstream of the partition. The combustion gases are introduced into the reactor upstream of the partition in a generally tangential direction for vortex flow while the make-hydrocarbon is introduced generally axially into the reactor.
