← ScienceWhich outcome occurs when the feed rate to a catalytic cracking reactor exceeds its design capacity?
A)Decreased conversion due to insufficient contact time✓
B)Increased catalyst activity from higher reactant concentration
C)Reduced reactor pressure from lower gas density
D)Enhanced heat transfer due to turbulent flow
💡 Explanation
When feed rate exceeds design capacity, reduced residence time occurs because reactants move through the reactor faster than designed, decreasing contact time between the feed and the catalyst, overall conversion decreases. Therefore, decreased conversion results, rather than increased activity, reduced pressure, or enhanced heat transfer which arise from different process changes.
