Synthetic Jet Fuel
A significant effort is under way to certify Fischer–Tropsch (FT) Synthesized Paraffinic Keroseen (SPK) synthetic fuels for use in U.S. and international aviation fleets. In this effort is being led by an industry coalition known as the Commercial Aviation Alternative Fuels Initiative (CAAFI), also supported by a parallel initiative under way in the U.S. Air Force, to certify FT fuel for use in all aviation platforms. The U.S. Air Force has a stated goal of certifying its entire fleet for use with FT synthetic fuel blends by 2011. The CAAFI initiative aims to certify the civilian aviation fleet for FT synthetic fuels blends by 2010, and has programs under way to certify Hydroprocessed Esters and Fatty Acids (HEFA) (aka Hydrogenated Renewable Jet (HRJ)) SPK biofuels as early as 2013. "Hydroprocessed" and "hydrotreated" have also been used in lieu of "hydrogenated". Both FT and HEFA based SPKs blended with JP-8 are specified in MIL-DTL-83133H.
Synthetic jet fuels show a reduction in pollutants such as SOx, NOx, particulate matter, and hydrocarbon emissions. It is envisaged that usage of synthetic jet fuels will increase air quality around airports which will be particularly advantageous at inner city airports.
- Qatar Airways became the first airline to operate a commercial flight on a 50:50 blend of synthetic Gas to Liquid (GTL) jet fuel and conventional jet fuel. The natural gas derived synthetic kerosene for the six-hour flight from London to Doha came from Shell’s GTL plant in Bintulu, Malaysia.
- The world's first passenger aircraft flight to use only synthetic jet fuel was from Lanseria International Airport to Cape Town International Airport on 22 September 2010. The fuel was developed by Sasol.

Famous quotes containing the words synthetic, jet and/or fuel:
“In every philosophical school, three thinkers succeed one another in the following way: the first produces out of himself the sap and seed, the second draws it out into threads and spins a synthetic web, and the third waits in this web for the sacrificial victims that are caught in it—and tries to live off philosophy.”
—Friedrich Nietzsche (1844–1900)
“I cannot beat off
Invincible modes of the sea, hearing:
Be a man my son by God.
He turned again
To the purring jet yellowing the murder story,
Deaf to the pathos circling in the air.”
—Allen Tate (1899–1979)
“It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world, the prince and the peasant, the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food. Neither could I do without them.”
—Henry David Thoreau (1817–1862)
