    摘要： A pipe, containing a multiplicity of spray ports spaced longitudinally along the pipe so that carbonaceous feedstock can be simultaneously ejected from the ports outwardly from the pipe, is adapted for concentric longitudinal, axial alignment in a carbon black reactor. Preferably the pipe is jacketed so that coolant fluid can be circulated through the annulus formed between the pipe and the jacket and conduit means provide a connection from the pipe to spray ports located in the jacket wall thereby providing means for ejecting carbonaceous feedstock outwardly from the jacketed pipe. A carbon black reactor containing a feedstock nozzle as described above with the nozzle adapted to eject hydrocarbon feedstock into either a precombustion or a combustion zone of the reactor. A method for producing carbon black in which hydrocarbon feedstock is introduced into either a precombustion or a combustion zone of a carbon black reactor through a feedstock nozzle as described above.

    摘要翻译： 管道，其包含沿着管道纵向间隔开的多个喷雾口，使得碳质原料可以从管道向外从孔口同时喷射，适于在炭黑反应器中同心纵向，轴向对准。 优选地，管被夹套使得冷却剂流体可以循环通过形成在管和护套之间的环形空间，并且导管装置提供从管道到位于护套壁中的喷雾口的连接，由此提供用于将碳质原料从夹套 管。 包含如上所述的原料喷嘴的炭黑反应器，喷嘴适于将烃原料排放到反应器的预燃烧或燃烧区域中。 如上所述，通过原料喷嘴将碳氢化合物原料引入炭黑反应器的预燃烧区域或燃烧区域中的生产炭黑的方法。

    摘要： 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.
