A process for producing carbon blacks having a lower surface area and structure wherein steam is introduced into the combustion gas stream at a point located a distance "L" from the point of introduction of feedstock (4) into the combustion gas stream such that the ratio of L/D ranges from 0 to less than 1.0, where "D" is the diameter of the zone (30) of the reactor at the point of introduction of feedstock.

La présente invention concerne un procédé de production de noir de carbone ayant une aire et une structure inférieures. De la vapeur est introduite dans le flux de gaz de combustion, en un point situé à une distance "L" du point d'introduction de la matière de départ (4) dans le passage des gaz de combustion, de telle sorte que le rapport L/D aille de 0 à moins de 1,0, "D" étant le diamètre de la zone (30) du réacteur au point d'introduction de la matière de départ.
