← ScienceWhich outcome occurs when platinum catalyst contamination increases in reformer reactors?
A)Reduced octane and increased aromatics✓
B)Enhanced hydrogen sulfide production rate
C)Formation of a thermodynamically stable siloxane
D)Increased C–C bond breaking activity
💡 Explanation
Reduced octane and aromatics result from increased Pt catalyst contamination because poisoning reduces active surface sites, lowering reforming efficiency via selective blocking, therefore undesirable products arise rather than desired ones, in suboptimal conversion conditions.
