Quantity of coke oven gas produced by high temperature carbonisation of one ton of dry coal may be around ______________ Nm3?
Correct answer: B. 300
- A. 30
- B. 300
- C. 3,000
- D. 30,000
Explanation
High-temperature carbonisation of one tonne of dry coal typically yields roughly 300 Nm³ of coke-oven gas, along with coke and tar. Values such as 30 or 3,000 Nm³ are respectively too low and too high for this process.
