← ScienceWhich outcome occurs when a packed-bed catalytic reactor experiences significant pressure drop?
A)Decreased reaction rate per catalyst✓
B)Increased heat transfer efficiency overall
C)Enhanced catalyst surface area exposure
D)Improved reactant mixing within bed
💡 Explanation
Pressure drop increases the residence time standard deviation, thus the effective reaction mixture deviates from ideal plug flow reaction resulting in decreased rate per catalyst, compared to expected yields because the mechanism reduces ideal reaction duration rather than enhancing performance.
