Abstract: A carbon black reactor is comprised of a housing which defines a precombustion zone, a reaction zone and a quench zone which are in flow communication. Inlet means open into the precombustion zone or the reaction zone and is operable to introduce make hydrocarbon into the reactor. Also, inlet means open into the precombustion zone and is operable for the introduction of hot combustion gases into the precombustion zone. The make hydrocarbon is pyrolyzed by contact with the hot combustion gases as same flow along the reaction zone. After a predetermined time as determined by the length of flow along the reaction zone, the effluent produced by the pyrolysis of the make hydrocarbon by contact with the combustion gases is quenched to stop the reaction.

Abstract: A carbon black reactor which has a precombustion zone and reaction zone therein with inlet means communicating with the precombustion zone for the introduction of hot combustion gases thereinto. A conduit communicates with the interior of the reactor and has mounted one one end thereof a nozzle for the discharge of make hydrocarbon into either the precombustion zone or reaction zone. A tubular member has an open end and surrounds a free end of the nozzle with the tubular member extending downstream of the free end whereby the open end of the tubular member permits flow of make hydrocarbon from the nozzle through the tubular member and out into the reactor.
