Octane number of gasoline produced by two stage fluidised catalytic cracking process is___________________?
Correct answer: D. 97
- A. 80
- B. 87
- C. 92
- D. 97
Explanation
Two-stage fluidised catalytic cracking gives a highly upgraded gasoline, with an octane number commonly quoted near 97. The lower values are more typical of less severe or older cracking operations.
