[perforatedplate]

Hi,

I am trying to model gas/solid multiphase granular flow with chemical reactions in Fluent. The solid phase is FCC catalyst together with the coke (hydrogen + carbon) deposited on its surface and the gas phase is oxygen. But I have some problems.

1. When modeling this, should I use both species transport and heterogeneous reactions in multiphase interaction module?
2. How to define solid phase in the materials section as FCC catalyst (granular) together with the coke (hydrogen + carbon) deposited on its surface?

Thanks...
