The difference between total carbon and fixed carbon of coal will be minimum in case of___________________?
Correct answer: D. High temperature coke (V.M < 0.5%)
- A. Lignite
- B. Bituminous coal
- C. Anthracite
- D. High temperature coke (V.M < 0.5%)
Explanation
The difference between total carbon and fixed carbon is smallest when volatile matter and other non-fixed carbon constituents are minimal. High-temperature coke has an especially low volatile-matter content, below about 0.5%.
