ABSTRACT:
A carbon black feedstock nozzle in which a central pipe with a diverging nozzle outlet is surrounded by at least one concentric annulus having a diverging nozzle outlet with a spray angle different from that of the central pipe and with means for supplying a separate controlled flow of inlet material to the central pipe and concentric annulus. In the preferred embodiment multiple concentric annuli surround the central pipe with the outermost annulus supplied with a coolant fluid as inlet material, and the other annuli supplied with hydrocarbon suitable as carbon black reactor feedstock. In a preferred embodiment means are provided for a seriatim cycling of flow through the various hydrocarbon feedstock annuli. A carbon black reactor in which a feedstock nozzle as described above discharges in a portion of the reactor that is either a precombustion section or a combustion section. A method for producing carbon black in which hydrocarbon feedstock is introduced into either a precombustion section or a combustion section of the carbon black reactor through a reactor feedstock nozzle as described above.
