Currently we have Media_0, Click on each media name to view and supply its chemistry, i.e., add (1) Media_0 : CO+O2 CO2. (2) NO+CO CO2 + N2

Click “Pre-Process” collects all the species from all the media.

Select the lower right edge, setting the outlet then proceed to set values we get:

Click on the media at the center. And from the left pane, change its Phase to Solid,Porous.
