Modeling of through-reactors with allowance of Large-Scale Effect on Heat and Mass Efficiency of Chemical Apparatuses

The first considered problem is the problem of arising dynamic dissipative structures in the chemical reactor volume. The mathematical model of heat and mass transfer in the tubular through-reactors has been submitted. The model consists of the diffusion-kinetic equations for two reagents under the first-order reversible reaction and heat transfer equation with allowance for the latent heat of reaction. Reaction rate constants for direct and reverse stages are related to temperature according to the Arrhenius law. The cases of both the adiabatic and non-adiabatic reactors have been considered. We consider the chemical conversion proceeding under the scheme of a reversible first-order reaction in a tubular through-reactor:
