ABSTRACT:
A carbon black reactor capable of producing carbon black of varying properties is disclosed comprising a longitudinally extending reactor tunnel having combustion, reaction, and quench zones in contiguous axial alignment. First and second venturi flow constrictions are provided in spaced relationship in the reaction zone of the reactor tunnel to create a pressure profile in the reaction zone. The pressure profile produces carbon blacks having certain physical properties. The second venturi constriction may be provided with means for varying the effective area of the second constriction for altering the pressure profile in the reactor tunnel to vary the properties of the produced carbon black. Further, carbon blacks of varying properties are produced for a given pressure profile by varying the point and direction of feedstock oil injection into the reaction zone.
