摘要： Carbon black is produced by heating a carbonaceous feed material to an elevated temperature to decompose the feed material to produce carbon black. A sample of the effluent from the reactor is passed as a suspension of carbon black particles in a gas into an optical cell. A beam of light is directed into the cell, and scattered light is measured at two different locations. A signal representative of the ratio of the two measured scattered light intensities is employed to control the introduction into the reactor of an alkali metal which controls the structure of the carbon black produced.
