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. A tubular member extends into the quench zone and has oppositely directed discharge openings on opposite sides thereof wherein a fluid coolant is introduced into the quench zone through the openings to form a curtain of coolant across the width of the quench zone through which the effluent must pass wherein same is cooled by contact with the coolant.
