The gas phase reversible reaction

is carried out under high pressure in a packed-bed reactor with pressure drop. The feed consists of both inerts I and Species A with the ratio of inerts to the species A being 2.5 to I. The molar flow rate of A is 5 moVmin at a temperature of 300 K and a concentration of 2.5 mol/dm3. Work this problem m terms of volume [Hint: V = W/p_B, r_A
= P_B
r’_A].

(a) Adiabatic Operation. Plot X, X_e, T and the rate of disappearance as a function of V up to V = 40 dm³. Explain why the curves look the way they do.

(b) Vary the ratio of inerts to A ( 0
 10) and the entering temperature and describe what you find.

(c) Plot the heat that must be removed along the reactor [ Q vs. V] to maintain isothermal operation. We will continue this problem in Chapter 12.
