Numerical solution of diffusive and convective transportation issues in heterogeneous catalytic processes involving hydrocarbons
D.B. TaghiyevThe regularities of catalytic reactions of cyclic hydrocarbons dehydration have been studied in the context of oxidizing dehydration of methylcyclopentane into cyclens. Changing relations of partial pressures and radial temperature profiles by the grain radius of oxide catalyst from time contact have been specified via the numerical analysis of reaction parameters and comparison of analysis results with theoretical calculations. The numerical study of convective-diffusive transportation issue in catalytic reaction involving hydrocarbons, where coefficients for rate and pressure calculation were obtained from experience in the context of oxidized dehydration of methylcyclopentane into the cyclens has been carried out. Final-incremental method for non-linear differential equations of convective-diffusive transportation issue with variable coefficients has been implemented. The approximation of transportation equation through differential scheme in considered catalytic system enables reducing significantly the number of spatial nodes, i.e. to decrease the amount of calculation operations.
