All of the following appear in the ultimate analysis of a coal EXCEPT

  • A.the hydrogen content of it
  • B.the sulphur content present
  • C.the volatile matter content
  • D.the carbon content of the fuel

Answer: C

Correct answer: the volatile matter content

Volatile matter belongs to the *proximate* analysis, which reports moisture, volatiles, fixed carbon and ash - a practical description of how the coal behaves. The ultimate analysis reports the elements: carbon, hydrogen, nitrogen, sulphur, oxygen and ash. The two are complementary and answer different questions.
