What is the primary component of natural gas used to create CNG?

Methane is the primary component of natural gas and serves as the main ingredient for compressed natural gas (CNG). CNG is largely composed of methane molecules, which consist of one carbon atom and four hydrogen atoms (CH4). This composition allows CNG to burn cleanly and efficiently, making it a popular choice for various applications, including fuel for vehicles.

Other components such as propane, butane, and ethane are found in natural gas but are typically present in much smaller amounts compared to methane. These other hydrocarbons can be used as fuel in their own right, but in the context of CNG, it is exclusively methane that is emphasized due to its predominance and the characteristics that make it suitable for use in engine fuel systems.
