Very ______________ coals are completely devoid of cokability i.e., it is non-coking ?
Correct answer: C. Both A & B
- A. Young
- B. Mature
- C. Both A & B
- D. Neither A nor B
Explanation
Very young coals such as lignite and very mature coals such as anthracite generally lack the plastic properties needed for coke formation. Coking behaviour is mainly associated with suitable intermediate-rank bituminous coal, so both extremes are non-coking.
