Which of the following is the most widely used cracking process in oil refineries ?
Correct answer: C. Fluidised bed catalytic cracking process
- A. Dubbs process
- B. T.C.C. moving bed process
- C. Fluidised bed catalytic cracking process
- D. Houdry's fixed bed process
Explanation
Fluidised-bed catalytic cracking, or FCC, is the dominant modern refinery cracking process because its continuously circulating catalyst provides high conversion and efficient regeneration. The older Dubbs, TCC moving-bed, and Houdry fixed-bed processes are less widely used.
