Could this be a Biodiesel ??? NO

The simple fact of the matter is that Kerosene has a freezing point of -71 degrees Celcius. You simply can't use Biodiesel because it would freeze solid at the -40 degrees typically reached at cruising altitudes.

If you do some research you will find that Syntroleum have already produced Biofuels using the Fisher-Tropsch process.

For the 747 you need some sort of a Bio-Kerosene
