Coal gas is a mixture of methane, hydrogen and carbon monoxide formed by the destructive distillation of coal. Petroleum gas obtained by fractional distillation of crude petroleum is a mixture of ethane, propane, and butane. Producer gas is formed by the partial burning of coal and contains gases like carbon monoxide and nitrogen. Natural gas is naturally occurring fossil fuel that contains all the alkanes.
