The order of preference for feedstock to a catalytic reformer is
A. Catalytic naphtha - coking naphtha - virgin naphtha
B. Coking naphtha - virgin naphtha - catalytic naphtha
C. Virgin naphtha - catalytic naphtha - coking naphtha
D. Virgin naphtha - coking naphtha - catalytic naphtha
Answer: Option D
Solution(By Examveda Team)
In petroleum refinery engineering, the order of preference for feedstock to a catalytic reformer is Virgin naphtha - coking naphtha - catalytic naphtha (Option D).Virgin naphtha: Virgin naphtha refers to the naphtha fraction obtained directly from the crude oil distillation process. It typically contains fewer impurities and is considered the highest quality naphtha for catalytic reforming.
Coking naphtha: Coking naphtha is obtained as a by-product from the thermal cracking or coking process. It may contain higher levels of impurities and may have a lower quality compared to virgin naphtha.
Catalytic naphtha: Catalytic naphtha is obtained from the catalytic reforming process itself. It is typically of lower quality compared to virgin naphtha and may contain more impurities.
Therefore, the correct order of preference is Virgin naphtha - coking naphtha - catalytic naphtha, making Option D the correct answer.
