Dear all,

For a design project I need to design a CSTR to convert nitrobenzene to para-aminophenol by catalytic hydrogenation using Pt/C. 

The nitrobenzene exists as a dispersed organic phase inside a continuous phase of sulfuric acid. I have obtained the rate of reaction and was going to use the design equation for a CSTR but my supervisor told me that because the reaction only takes place inside the dispersed phase that I need to model each nitrobenzene drop like a small PFR and use a different design equation for calculating the reactor volume. 

I don't really understand why and was hoping someone could explain this to me.
