<P> Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust . However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel . Emulsified fuels of oil - in - water such as orimulsion have been developed a way to make heavy oil fractions usable as liquid fuels . Many liquid fuels play a primary role in transportation and the economy . </P> <P> Some common properties of liquid fuels are that they are easy to transport, and can be handled with relative ease . Also they are relatively easy to use for all engineering applications, and home use . Fuels like kerosene are rationed in some countries, for example available in government subsidized shops in India for home use . </P> <P> Conventional diesel is similar to gasoline in that it is a mixture of aliphatic hydrocarbons extracted from petroleum . Kerosene is used in kerosene lamps and as a fuel for cooking, heating, and small engines . Natural gas, composed chiefly of methane, can only exist as a liquid at very low temperatures (regardless of pressure), which limits its direct use as a liquid fuel in most applications . LP gas is a mixture of propane and butane, both of which are easily compressible gases under standard atmospheric conditions . It offers many of the advantages of compressed natural gas (CNG), but is denser than air, does not burn as cleanly, and is much more easily compressed . Commonly used for cooking and space heating, LP gas and compressed propane are seeing increased use in motorized vehicles; propane is the third most commonly used motor fuel globally . </P> <P> Fuel gas is any one of a number of fuels that under ordinary conditions are gaseous . Many fuel gases are composed of hydrocarbons (such as methane or propane), hydrogen, carbon monoxide, or mixtures thereof . Such gases are sources of potential heat energy or light energy that can be readily transmitted and distributed through pipes from the point of origin directly to the place of consumption . Fuel gas is contrasted with liquid fuels and from solid fuels, though some fuel gases are liquefied for storage or transport . While their gaseous nature can be advantageous, avoiding the difficulty of transporting solid fuel and the dangers of spillage inherent in liquid fuels, it can also be dangerous . It is possible for a fuel gas to be undetected and collect in certain areas, leading to the risk of a gas explosion . For this reason, odorizers are added to most fuel gases so that they may be detected by a distinct smell . The most common type of fuel gas in current use is natural gas . </P>
