The ratio of % total carbon obtained in the ultimate analysis of coke and % fixed carbon obtained in the proximate analysis is always ___________________?
Correct answer: C. > 1
- A. 1
- B. < 1
- C. > 1
- D. Unpredictable
Explanation
Ultimate analysis measures all carbon, including carbon present in the volatile matter, whereas proximate fixed carbon excludes that portion. Therefore, the total-carbon percentage is greater than the fixed-carbon percentage.
