Answer 2

Compressed Natural Gas (CNG) is composed primarily of methane (CH4), with small amounts of other hydrocarbons such as ethane, propane, and butane. Methane content typically ranges from 85-98%, with the remaining components making up the rest.

Answer 3

Compressed Natural Gas (CNG) is primarily composed of methane (CH4), with a composition of around 85-98%. It also contains small amounts of other hydrocarbons such as ethane, propane, and butane, as well as trace amounts of nitrogen, carbon dioxide, and hydrogen sulfide. The exact composition can vary depending on the source and production methods used.
