Abstract (en)
[origin: WO9634918A1] 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.
