Q#4: Consider the following system of gas-phase reactions:
A
x = k₁C₁¹/2
A-
B
k, = 0.004 (mole/dm³)¹/² min
k₂ = 0.3 min¹¹
ky = 0.25 dm³/mole.min
rg = K₂C₁
Y
ry=k₂C₁²
B is the desired product and X and Y are foul pollutants that are expensive to get rid of. The specific reaction rates are
at 27 °C. The reaction system is to be operated at 27 °C and 4 atm. Pure A enters the system at a volumetric flow rate
of 10 dm³/min.
1) Sketch the instantaneous selectivity (S) as a function of the concentration of CA
2) Consider a series of reactors. What should be the volume of the first reactor?
3) What are the effluent concentrations of A, B, X and Y from the first reactor?
4) What is the conversion of A in the first reactor?
