Process for the production of furnace black by producing a stream of hot combustion gases in a combustion chamber, feeding the hot combustion gases along a flow axis from the combustion chamber through a reactor narrow point into a reaction zone, mixing carbon black raw material into the flow of the combustion gases in front of, inside or behind the reactor narrow point and stopping carbon black formation downstream in the reaction zone by spraying in water, steam being jetted in axially through the gas burner and optionally at the radial oil nozzles and beaded carbon black being introduced before and/or after the reactor narrow point.

Process for the production of furnace black

A tubular furnace as a reactor for producing carbon black is disclosed having a constriction in at least the area of the spray device for the carbon black starting material which is oriented along the reactor axis. A combination chamber for generating the gaseous pyrolysis medium for the carbon black raw material is laterally located in front of the constriction. The central axes of the reactor tube and the combustion chamber are in the same plane and are essentially at right angles to one another. In addition, a method for producing furnace carbon blacks is disclosed in which the described reactor can be used for forming a highly turbulent, yet essentially non-swirling flow of combustion gases into which the carbon black starting material is injected.
