In high temperature carbonisation (as compared to low temperature carbonisation) of coal, the______________?
Correct answer: A. Aromatic content of tar produced is more
- A. Aromatic content of tar produced is more
- B. Tar yield is more
- C. Ignition temperature of coke produced is less
- D. Gas yield is less
Explanation
High-temperature carbonisation produces tar with a greater proportion of aromatic compounds because stronger thermal cracking and condensation reactions occur. Low-temperature carbonisation generally gives more tar, but it is less aromatic.
