Pick out the correct statement pertaining to catalytic cracking ?
Correct answer: C. All A., B. and C.
- A. With increase in the reactor pressure, octane number of gasoline decreases
- B. With increase in the reactor temperature, gasoline yield decreases for a given conversion
- C. All A., B. and C.
- D. Percentage conversion increases with increase in the catalyst to oil ratio
Explanation
Increasing the catalyst-to-oil ratio generally increases conversion, while higher reactor pressure tends to reduce gasoline octane. At a fixed conversion, higher temperature promotes secondary cracking, so gasoline yield decreases and all three statements are acceptable.
