Which of the following processes is used for the production of petroleum coke ?
Correct answer: C. Cracking
- A. Stabilisation
- B. Visbreaking
- C. Cracking
- D. Reforming
Explanation
Petroleum coke is produced by coking, particularly delayed coking, in which heavy residues undergo severe thermal cracking and leave a carbon-rich solid. Stabilisation, reforming, and visbreaking do not normally produce petroleum coke as their main product.
