摘要

A method for controlling the aggregate size and structure of the carbon blacks produced by a furnace carbon black reactor by lowering the temperature of, but not stopping pyrolysis in, the effluent (the mixture of combustion gases and feedstock in which pyrolysis is occurring), up to 426.7 DEG C and preferably between 10 and 426.7 DEG C at a residence time between 0.0 second and 0.002 second downstream from the furthest downstream point of injection of feedstock. <IMAGE>
