text: We have unexpectedly found that certain conditions for introducing the auxiliary gas, including a decreased injection orifice diameter, increased feed rate, and injection of the auxiliary gas in the same axial plane as the carbon-black yielding feedstock, in combination with specific concentrations of alkali and/or alkaline earth elements in the feedstock, as well as specific diameters and lengths for the various combustion zones, enabled us to produce carbon blacks having both low structure and high surface area.
