Propane is an alkane with the chemical formula C3H8. As a type of hydrocarbon, it can undergo hydrocarbon combustion, which gives off heat. Propane is one of the hydrocarbon components of raw natural gas, which is a type of fossil fuel. Propane is usually removed from natural gas before being shipped to customers, but is also sold separately as a fuel on its own.
Propane is normally in a gaseous state during consumption. However, it is normally stored as a liquefied propane gas in tanks such as the one shown in Figure 2. Propane has one of the highest energy densities (50.3 MJ/kg) of any hydrocarbon, second only to methane.
Below is a table of some of the basic properties of propane.
