← ScienceWhich risk increases when heterogeneous catalysts in a packed bed reactor experience channeling?
A)Runaway reaction due to reduced efficiency✓
B)Increased catalyst attrition from higher pressure
C)Decreased product selectivity from slow reactions
D)Enhanced heat transfer due to turbulent mixing
💡 Explanation
Runaway reaction risk increases because bypassing flow reduces reactant contact during catalytic activity, impairing the heat removal mechanism; therefore, the heat is not effectively removed, rising dramatically, rather than maintaining control by design.
