Simulation of the non-stationary behavior of packed-bed reactors for the determination of kinetic expressions in consideration of a non-homogeneous concentration profile in the catalyst pellets

For the modeling of non-stationary catalyst, behavior kinetic expressions t hat were measured under non-stationary conditions, thus, resulting in more information about the single steps of the adsorption, reaction, and desorpt ion, are required. The authors present a program that allows the simulation of chemical reactor dynamics without having to assume a homogeneous concen tration or temperature profile inside the pellets.
