In high temperature carbonisation of coal compared to low temperature carbonisation ?
Correct answer: C. H2 content in the coke oven gas is more
- A. Yield of ammonia is less
- B. Aromatic content of tar is low
- C. H2 content in the coke oven gas is more
- 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.
