An axial flow carbon black reactor for producing carbon black particles having a relatively narrow particle size distribution. Feedstock oil is introduced into the reactor by a spray nozzle located coaxial with the longitudinal center line of the reactor. The oil spray flows either in the countercurrent or the concurrent direction relative to the flow of hot gas through the reactor and produces an oil spray pattern covering either substantially the entire frontal area of the hot gas flow or substantially less than the frontal area. Countercurrent feedstock flow increases coverage of the gas flow area by the oil spray and narrows the particle size distribution of carbon black produced bythe reactor, and concurrent feedstock flow produces the opposite result.
