CNG — Compressed Natural Gas. It is used as a fuel. All liquid fuels are formed from petroleum. Butane is the main constituent of LPG. Petroleum was formed by the sedimentation of dead remains of microscopic marine plants and animals, which were buried under the surface of the earth, millions of years ago. Green leaves do not catch fire easily because they contain moisture.
