CDP6-MB

The elementary gas-phase isomerization reaction

A → B

is carried out in a packed-bed recycle reactor. The recycle ratio is 5 mol recycled per mole taken off in the exit stream. For a volumetric flow rate of 10 dm 3 /s through the reactor (Figure CDP6-L), the corresponding pressure gradient (assumed constant) in the reactor is 0.0025 atm/ m. The flow in the reactor is turbulent. What overall conversion can be achieved in a reactor that is 10 m in length and 0.02 m 2 in cross-sectional area?

Additional information:

C A0 =0.01 mol /dm 3 (P 0 = 2 atm). The volumetric flow rate of fresh reactant to the reactor is 0 = 10 dm 3 /s. The specific reaction rate is k = 0.25 s -1 .
