Coal gas obtained by carbonisation contains as its principal combustible constituents

  • A.carbon dioxide and nitrogen
  • B.carbon monoxide and nitrogen
  • C.acetylene and ethylene only
  • D.hydrogen and methane

Answer: D

Hydrogen makes up about half the volume and methane a further third, with some carbon monoxide, so the calorific value is far above that of producer gas. Tar, ammonia and benzole are recovered as by-products of the same process.
