A carbon black process is disclosed wherein a reactor is employed having in open axial alignment and operatively connected with each other an axial zone, an enlarged precombustion zone and a smaller Venturi-shaped reaction zone. Into this reactor hydrocarbon feed is axially introduced, from 90 to 30 volume percent of the gases forming the hot combustion gases are introduced tangentially into the precombustion zone, and from 10 to about 70 volume percent of these gases are introduced into the axial zone. In a preferred embodiment the carbon black reactor has an axial zone with an internal diameter of about 1.5 to about 3 times the diameter of the throat of the Venturi-shaped reaction section.
