Volatile matter content of metallurgical coke may be around ______________ percent?
Correct answer: A. 1-2
- A. 1-2
- B. 10-15
- C. 22-26
- D. 30-33
Explanation
Metallurgical coke is strongly devolatilised during coking, so its volatile matter is typically only about 1 to 2 percent. Values such as 10 percent or more are characteristic of less thoroughly carbonised coal products.
