Question
Problem 1.
The following table was obtained from the data taken in a slurry reactor
for the hydrogenation of methyl linoleate to form methyl oleate.
L+H₂
S = solubility of H2 in the liquid mixture, mol/dm³
m = catalyst charge, g/dm³
-r₁₁ = rate of reaction of methyl linoleate, mol/dm³/min
Catalyst Size S/-r' (min) 1/m (dm³/g)

a. Which catalyst size has the smaller effectiveness factor?
b. If catalyst size A is to be used in the reactor at a concentration of
50 g/dm³, would a significant increase in the reaction be obtained
if a more efficient gas sparger were used?
c. If catalyst size B is to be used, what is the minimum catalyst
charge that should be used to ensure that the combined
diffusional resistances for the pellet are less than 50% of the total
resistance?
