such as hydrogen fuel (for automotive uses), ethanol, jet fuel and bio-diesel, which are all categorized as liquid fuels. Emulsified fuels of oil in water...

fossil fuels typically requires a geological process of millions of years. Due to the length of time it takes nature to form them, fossil fuels are considered...

Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used...

fuel oil refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel...

mixtures. Most jet fuels in use since the end of World War II are kerosene-based. Both British and American standards for jet fuels were first established...
