With increases in carbonisation temperature_______________________?
Correct answer: A. Coke even gas yield increases
- A. Coke even gas yield increases
- B. Tar yield increases
- C. Hydrogen percentage in the coke oven gas decreases
- D. Methane percentage in the coke oven gas increases
Explanation
Increasing carbonisation temperature promotes secondary cracking and gas formation, so coke-oven gas yield increases. Tar and methane generally decrease, while hydrogen tends to increase rather than decrease.
