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.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
