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.
