Hydrocarbon combustion - Energy Education

Hydrocarbon combustion. Español. Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. They are most famous for being the primary constituent of fossil fuels, namely natural gas, petroleum, and coal.

Because oil is primarily made of carbon (C) and hydrogen (H), we sometimes refer to it as a hydrocarbon. Methane is the simplest hydrocarbon, CH 4, but oil contains a great range of larger hydrocarbon molecules, such as octane (C 8 H 18 ). With too much heat, the oil breaks down to make methane. This gas is also produced as coal forms.
