Problem 4 [10 marks] The 1st order gas phase reversible reaction is happening in a catalytic membrane reactor in isothermal condition. AB+2C Pure A enters the reactor and only species B diffuses through the membrane. RB is the molar flow of species B through the membrane per unit wt. of catalyst. And FAO is the inlet molar flow rate of species A. There is a pressure drop in the reactor side with pressure drop parameter a(kg1). [a] Write down the net rate for A ? (1 mark) [b] Write down the rate of species B and C in terms of reaction rate of A ? ( 1 mark) [c] Write down the mole balance for species A, B, C (per wt. of catalyst, i.e., dWdFA=) ? (Show the steps from generalized mole balance) (4 marks) [d] Write down the concentration of species A, B, C in terms of molar flow rate?(2 marks) [e] Write down the pressure drop differential equation in terms of molar flow rate. (2 marks) Hints: Generalized mole balance IN - OUT + GENERATION = ACCUMULATION Differential equations must be derived using wt. of catalyst. Such as, (dWdFA)
