Prior to the 1960s, ethane and larger molecules were typically not separated from the methane component of natural gas, but simply burnt along with the methane as a fuel. Today, ethane is an important petrochemical feedstock and is separated from the other components of natural gas in most well-developed gas fields.

Water gas is a kind of fuel gas, a mixture of carbon monoxide and hydrogen. It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam". It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam".
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
The heating value of a fuel can be calculated with the results of ultimate analysis of fuel. From analysis, percentages of the combustibles in the fuel (carbon, hydrogen, sulfur) are known. Since the heat of combustion of these elements is known, the heating value can be calculated using Dulong's Formula:
Petroleum fuels, when burnt, release carbon dioxide that is necessary for plant growth, but which (given the large scale of global emissions) is potentially harmful to world climate. The amount of carbon dioxide released when one liter of fuel is combusted can be estimated: [1] As a good approximation the chemical formula of e.g. diesel is C n ...
Crude oil is processed in several stages to form desired hydrocarbons, used as fuel and in other products. Tank wagon 33 80 7920 362–0 with hydrocarbon gas at Bahnhof Enns (2018) The predominant use of hydrocarbons is as a combustible fuel source. Methane is the predominant component of natural gas.
