Question

The main component of compressed natural gas (CNG) is
1. ethane
2. methane
3. butane
4. None of the above

Answer 1

Correct Answer - Option 2 : methane

The correct answer is Methane.

• The major component of bio-gas and Compressed Natural Gas (CNG) is Methane.

 

• Bio-CNG contains about 92-98 % of methane and only 2-8 % carbon dioxide.
  • The high methane content and calorific value combined with the low quantity of moisture, hydrogen sulphide and impurities makes Bio-CNG an ideal fuel for automobiles and power generation.
• Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG).
  • CNG is made by compressing natural gas, which is mainly composed of methane (CH4).

Fuel Gases	Major component	Uses
Compressed natural gas (CNG)	Methane Ethane	Can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG)
Liquefied petroleum gas (LPG)	Butane Propane	LPG is used for cooking. An alternative to electric heating, heating oil, or kerosene. As it is odourless so Methyl Mercaptan is added to it so there may be smell if LPG leak from its storage container.
