Abstract

Improved method for manufacturing oil furnace carbon blacks comprising continuously introducing a combustion mixture of hydrocarbon fuel and air into a converging section of an elongated reaction zone, said converging section leading to a neck followed by a diverging section, and by continuously injecting a normally liquid hydrocarbon feed charge into said reaction zone so as to mix with the combustion products of said fuel-air combustion mixture, and cooling the reaction after a certain reaction time, the improvement that it comprises adjusting the reactor dimensions, operating conditions and reaction time to form carbon black from the family of carbon blacks having iodine numbers within the range 60-150, said family having the following relationship between the number of iodine, persistent stain and structure (24M4). **(See formula)** Said reactor dimensions, operating conditions and reaction times are as follows: Air supply rate 3680.95-5663 m3/h Feed oil supply rate 863.74-1181.96 liters/hour Fuel air/gas ratio 12/1-17/1 Nozzle feeding distance to the neck 761.99-1523.98 millimeters. Distance from the tuner to the neck 1219-2438 millimeters. Distance from the feed nozzle to the quencher 2438-3658 millimeters. Reaction temperature 1648-1815ºC Total reaction time, milliseconds 13-40 Reaction time, material injection Neck feeding, 3-10 milliseconds.
