Modeling Packed Bed Reactors with COMSOL Web Workshop
Packed bed reactors are commonly used in chemical processing applications such as absorption, distillation, stripping, separation processes, and catalytic reactions. The main advantage of these reactors is that they significantly increase the available surface area for the catalyst, which increases the rate of the chemical reaction. The reactant gases or liquids flow over the pellets, whose microscale pores allow the reactants to flow or diffuse through the pellets and react, and then the products of the reactions leave the pellets.
As there can be hundreds or thousands of pellets, and each pellet contains microscale pores, it would be extremely challenging and computationally intensive to resolve all of the geometrical details of the reactor. COMSOL Multiphysics® offers a streamlined alternative solution, with dedicated features for efficiently modeling packed bed reactors.
During this web workshop, we will introduce these features and discuss how the COMSOL® software can be used to:
- Efficiently model flow through porous media.
- Model dilute and concentrated chemical species transport in porous domains.
- Include bulk reactions, heterogeneous reactions, surface reactions, and equilibrium and nonequilibrium adsorption, as well as reactions occurring inside the porous pellets themselves, when modeling packed bed reactors.
- Model heat transfer in the surrounding fluid and the porous domain with increasing levels of detail. We will discuss the Local thermal equilibrium, Local thermal nonequilibrium, and Packed bed approaches.
