Which is a catalyst promoter used in catalytic ammonia synthesis reaction ?
Correct answer: C. K2O
- A. Al2O3
- B. Cr2O3
- C. K2O
- D. MnO
Explanation
Ammonia synthesis uses promoted iron, with K2O acting as an electronic promoter that improves catalyst performance. Alumina and other oxides can provide structural promotion, but K2O is the standard promoter listed here.
