In high temperature carbonisation of coal compared to low temperature carbonisation ?
Correct answer: A. H2 content in the coke oven gas is more
- A. H2 content in the coke oven gas is more
- B. Aromatic content of tar is low
- C. Yield of ammonia is less
- D. Calorific value of the coke oven gas is lower
Explanation
High-temperature carbonisation produces coke-oven gas richer in hydrogen, while low-temperature carbonisation gives gas richer in heavier hydrocarbons. Hence, the hydrogen content is higher in the high-temperature process.
