Propane is catalytically dehydrogenated to produce propylene by passing it over a granular solid catalyst. In parallel with the main gas-phase reaction of propane dehydrogenation, a side reaction to methane and carbon occurs:

C3H8 = C3H6+H2

C3H8 = 2CH4+C

A conversion of propane of 80% is achieved in the reactor of the propane reacting, 20% reacts according to the side reaction.

Using a basis of 100 kmol/hr fresh feed of pure propane calculate the reactor outlet composition and flows.
