Which risk increases when attempting elevated space-velocity in packed catalysts?

A)Increased catalyst bed temperature runaway
B)Decreased residence time for reactants
C)Reduced overall equilibrium constant
D)Greater diffusional mass-transfer limitations

💡 Explanation

Increasing space-velocity can lead to inadequate heat removal from exothermic reactions; therefore, thermal expansion may occur leading to catalyst bed temperature runaway because more heat is formed than removed, rather than limitations in mass transfer.
