Annotation | The work is devoted to a numerical study of the propagation of the combustion front in a fixed catalyst layer with a spherical grain shape during heterogeneous chemical reactions with a detailed description of the kinetics using the example of burning coke sedimentation from the catalyst layer. The mathematical model describing the burning is a system of equations of mathematical physics with initial boundary conditions. The computational algorithm for the system is based on the principle of splitting by physical processes with the selection of adequate integration methods for each of them. The combustion front is described as a heat wave moving through the catalyst layer. The model implements a dynamic burning mode, which consists in supplying a reaction mixture of variable temperature and composition. The analysis of the calculation results revealed the advantages of dynamic burning over stationary. |
