Modeling and Simulation of Packed Bed Reactors

In industrial reactors there are normally gradients in the species mass concentrations, temperature, pressure and velocity in all space directions. The fundamental microscopic equations give a detailed description of all the known mechanisms involved. 

In industrial reactors there are normally gradients in the species mass concentrations, temperature, pressure and velocity in all space directions. The fundamental microscopic equations give a detailed description of all the known mechanisms involved. In the chemical reactor engineering approach we desire to eliminate the mechanisms that is not essential for the reactor performance from the equations to reduce the computational demand. An appropriate engineering packed bed reactor model is thus tailored for its main purpose. It is as simple as possible, but still include a sufficient representation of essential mechanisms involved. 

The axial dispersion terms may be required to account for the mixing phenomena created by a non-ideal flow. However, the ideal plug flow model is often appropriate for packed bed reactors because the axial mixing is negligible compared to the convective flux for many processes.
