Carbonaceous Particulate Matter (PM) emitted from combustion field is industrially produced as carbon black (CB) and used in a variety of products. In this study, to clarify characteristics of PM emitted by flame quenching process, a laminar pool flame of toluene was quenched using a slide and rotary metal mesh system, and PM emitted by quenching process was analyzed. Size distribution and oxidation characteristics of PM emitted by quenching at various heights in the flame were measured by a Low Pressure Impactor (LPI) and a Thermo Gravimetric Analyzer (TGA). In addition, the activation energy was analyzed using the result of TGA.
