Default how to simulate hetergeneous reation in fixed bed reactor

cen is on a distinguished road
Hello everyone,
I am working with a simulation of heterogeneous reaction (gas-liquid phase with solid catalyst) in fixed bed reactor.
Physical model I chose:
• Eulerian multiphase
• Gradients
• Multiphase Equation of State
• Multiphase Interaction
• Multiphase Segregated Flow
• Phase Couple Fluid Energy
• Steady
• Three Dimensional
And I set the region as porous Region and defined 2 phases (1 multi-component liquid and 1 multi-component gas) and then specified the liquid as continuums phase and the gas as dispersed phase.
But after selecting the Interphase Mass Transfer Model, what I got from the Interphase Mass Transfer Rate group box doesn't include Interphase reaction, there are only Boiling Mass Transfer Rate and UD Interphase Mass Flux.
What can I do to activate the Interphase reaction?
And how can I define the catalyst in this case?
Thanks for helping!!
