Problem 1 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: C₂H₂ →C,H, +H₂ C,H, 2CH +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.h¹ fresh feed of pure propane calculate the reactor outlet composition and flows.
