Abstract

Aviation fuels commonly used today are extracted from the kerosene fraction of the crude oil that is distilled between the gasoline and the diesel. Crude oil is not renewable and the world oil reserve is generally believed to be on the decline. In 2006, 6.3% of the world's refinery production was used for aviation fuel (Nygren et. al., 2009). At an estimated rate of 3% increase of fuel demand per year, aviation use alone will consume the world fuel production by 2026. Therefore, there is a need for the aviation industry to reduce its dependence on fossil fuels and, perhaps, replace them with alternative, renewable fuel. Biofuel is a fuel obtainable from biological material and can exist in the form of solid, liquid, or gas. Unlike fossil fuel, which is derived from fossils of biological material, biofuel is renewable. Biofuel also has the advantage of biosequestration of the atmospheric CO₂ and, therefore, helps remediate greenhouse gases and, possibly, climate change.
