Carbon Deposition in Heterogeneous Catalysis
Application ID: 1968
Carbon deposition on the surface of solid catalysts is commonly observed in hydrocarbon processing. A known problem is that carbon deposits can impede the activity of catalysts as well as block the flow of gas through a catalyst bed.
This example investigates the thermal decomposition of methane into hydrogen and solid carbon, over a catalyst. The influence on the catalyst activity is first studied with the Reaction Engineering interface in an ideal reactor model. This is extended to a space and time dependent model where the porosity decay due to carbon deposition is accounted for.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Chemical Reaction Engineering Module and
- either the Battery Design Module, CFD Module, Chemical Reaction Engineering Module, or Fuel Cell & Electrolyzer Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
