Abstract: A method and apparatus for making carbon black having increased surface area, reduced grit and/or reduced extract levels. A plasma gas is flowed into a plasma forming region to form a plasma. The plasma then flows through a throat region which is narrower than the plasma forming section, which is connected to a separate carbon black forming region. This causes the plasma to accelerate and become turbulent prior to the exit point in the throat region. The carbon black forming feedstock is injected into the turbulence created by the throat region at a point above, at or near the exit point, resulting in the formation of a carbon black in the separate carbon black forming region. The throat region and/or injector region can be cooled, e.g., water plasma gas cooled.

Abstract: Secondary heat may be added to a particle production process. The particles may be, for example, carbon particles. Among other things, the secondary heat addition may result in change in surface area of the carbon particle(s), change in structure of the carbon particle(s), reduced wall fouling, reduced energy consumption and/or increased throughput. Apparatus for performing the process is also described.
