A method and apparatus for controlling in a continuous fashion the surface area of carbon black being produced in the carbon black formation zone of a carbon black reactor. Specifically, this invention is a method and apparatus for maintaining uniform surface area of a particular grade of carbon black while it is being produced continuously by an oil furnace process. The process parameters, such as rate flow of an oxidation material, of a combustion material, and of a hydrocarbon feedstock material as well as the quality (composition) and temperature of each of these materials may be altered based upon the temperature of the flowing mass as measured in the reaction zone of a carbon black reactor. The temperature measured within the reaction zone then can be used as an indicator of the particle size of the carbon black since an adjustment to rate of flow, quantity, and temperature of each material affects the end product.
