Properties of nanoparticles are size-dependent, therefore nucleation and growth of particle is often difficult. The population balance model has been developed to study the mechanism of nanoparticles formation in high temperature reactor. Processes responsible for particle formation and growth are considered by homogeneous nucleation, condensation and Brownian coagulation. Parameters such as temperature, residence time and reactant concentrations influencing particle size are investigated. The population balance model is the dynamic model that describes the evolution of the aerosol size distribution with time. The method of moments was used to solve the dynamic equation under the assumption of log-normal size distribution. The model was validated with existing model.
