Coal tar fuels (CTF) as compared to petroleum based fuel oils have higher __________________?
Correct answer: D. Higher C/H ratio
- A. Calorific value
- B. Difference in gross & net calorific value
- C. Sulphur content
- D. Higher C/H ratio
Explanation
Coal-tar fuels contain more aromatic and carbon-rich constituents than petroleum fuel oils, giving them a higher carbon-to-hydrogen ratio. Their calorific value is not necessarily higher, so the C/H ratio is the distinguishing property.
