Abstract:The objective of the present study is to examine the impact of nucleation behavior and particle size distribution on morphology of carbon black. We used a fixed sectional approach applying the detailed chemical kinetic reaction , and calculated for our previous experimental work which was the pyrolysis of benzene in an inert atmosphere. From comparison the numerical behavior of PAHs formation and nucleation with experimental configurations of carbon black, the impacts of behavior of PAHs formation and nucleation on configurations were discussed. In addition, the parametric study was carried to investigate the effect of the furnace temperature on the nucleation behavior. The numerical results at 1573 and 1673 K predicted very well the experimental, while the numerical result at 1473 K underpredicted the experimental. This difference can be responsible for the temperature range of the used kinetic model. The molar concentration and formation ratio of nuclei increased with an increase in furnace temperature. The experimental configurations became complex at 1673 K and short residence time. They suggest that high nucleation rate and high concentration complex the configurations of carbon black. The nuclei concentration peaked around 1673–1750 K by parametric study.
