Naphtha is a flammable liquid made from distilling petroleum. It looks like gasoline. Naphtha is used to dilute heavy oil to help move it through pipelines, to make high-octane gas, to make lighter fluid, and even to clean metal.
LNG is normally warmed to make natural gas to be used in heating and cooking as well as electricity generation and other industrial uses. LNG can also be kept as a liquid to be used as an alternative transportation fuel.
LPG commonly is used as fuel for gas barbecue grills and gas cooktops and ovens, for gas fireplaces, and in portable heaters. In Europe, LPG water heaters are common. It is also used as an engine fuel and for backup generators. Unlike diesel, LPG can be stored nearly indefinitely without degradation.
In its natural state gasoline is a liquid with a strong solvent smell. Typically it is used to fuel internal combustion engines for cars, motorbikes, trucks, boats and other transport vehicles.
Examples of fuel oil uses include heating up homes and fuel trucks to lighting up furnaces, producing steam for industrial uses and for generating electric energy. It is produced from the burnable liquids derived from crude oil and is also called kerosene, home heating oil, diesel fuel or coal oil.
Crude oil is the base for lots of products. These include transportation fuels such as gasoline, diesel, and jet fuel. They also include fuel oils used for heating and electricity generation.
