Describe methane and ethane fuel gas preperation

 Methane and ethane are found in natural gas.

• Natural gas is taken from underground deposits and cleaned.
• The cleaned gas is moved through pipelines or compressed for storage.
• Methane and ethane can also be made by heating up oil or other substances, using a process called thermal or catalytic cracking.
• Anaerobic digestion can be used to make methane and ethane from organic matter by breaking it down without oxygen.
• Methane and ethane can also be made by heating coal in the presence of steam and air, which produces a gas that contains them and other gases.
