    Abstract: Carbon black is produced in a flow reaction by spraying a hydrocarbon containing liquid feedstock with the aid of a propellant gas into a stream of hot reaction gases produced by burning a fuel, the feedstock-propellant gas-jet enters the reaction zone with a spraying angle that is greater than the spreading angle of a free jet. There is also described an apparatus for carrying out the process which comprises a binary injector supporting an atomizing nozzle whose head has several channels which are adjusted from zero degrees to different angles to the longitudinal axis of the nozzle.

    Abstract: Furnace black is produced by a thermal splitting of a carbon black forming oil by oxidation of a fuel in a combustion chamber with production of a stream of hot combustion gases, introduction of this stream in a constricted mixing chamber narrower than the fuel chamber, inserting the carbon black forming material into the mixing chamber and conveying the mixture into an enlarged reaction chamber compared to the mixing chamber as well as quenching the carbon black containing reaction mixture, the stream of hot combustion gases being introduced into the mixing chamber via an annular channel or introducing the stream into an annular channel shaped mixing chamber and spraying in the carbon black forming material into the mixing chamber or ring conduit from within outwardly.

    Abstract: A process for the production of furnace carbon blacks with a faint structure produced by the addition of alkali metal salts is described. An intimate mixture of the liquid carbon black oil and of the solution of the structure-reducing additive is produced in one or more static mixers and is fed to the reactor. The carbon black formed is grit-free. The invention furthermore relates to an apparatus for carrying out the process.
