Correct answer: A. All A, B. and C.
- A. All A, B. and C.
- B. Sintering of porous catalyst
- C. Hydrogen embrittlement
- D. Pyrolysis of oil
Explanation
Excessive temperature during oil hydrogenation can cause oil pyrolysis, damage or sinter the porous catalyst, and promote hydrogen-related embrittlement of equipment. Thus, when all listed effects are intended, the combined choice is appropriate.
