N2 - To establish the influence of hydrocarbon raw materials composition, duration and temperature of a reaction on the dispersion and structural properties of the carbon black produced in a reactor, two numerical three-dimensional models for the reactor operation process are proposed. These models are made in the approximation of the Eulerian-Eulerian approach and implemented on the FlowVision PC and ANSYS PC platforms. In the FlowVision model a convection-diffusion equations for the dispersed phase are used. In ANSYS PC, the movement of the dispersed phase is described by the Navier-Stokes equations. The article also analyzes a model for describing the nucleation and growth of carbon black particles. The Moss-Brookes model of uncontrolled formation of soot particles during acetylene combustion was taken as the basis for the model of carbon black formation in the reactor. To generalize it to carbon black production in a reactor under harsh pyrolysis conditions at a temperature no lower than 1000 ◦C and a high degree of reactions heterogeneity, a number of techniques are proposed. The numerical results of modeling the spray atomization and evaporation of raw materials processes in the reactor are presented. The sensitivity of the mass and carbon black particles quantaty on the constructed model input parameters was analyzed.
