ABSTRACT:
Disclosed is a method of making a carbon black product having a controllable aggregate particle size distribution comprising forming in a first zone of the carbon black reactor combustion gases at a high temperature and having a gradient of increasing turbulence in the downstream direction, injecting substantially radially into the first zone a carbon black feedstock into more than one of the "zones of increasing turbulence" before the gases reach maximum turbulence, cracking the feedstock to carbon black in a second (reaction) zone, quenching the carbon black reaction, and collecting the carbon black product. Also discussed is a method for making a carbon black product having varying physical characteristics as a result of modifying reaction kinetics at any position of oil injection into the "zones of turbulence".
