Secondary heat addition to particle production process and apparatus

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.
