Aviation fuels are widely substituted by the biofules produced from the jartopha oil than any other fuels. To meet the increasing demand of the jet fuels jartopha oil can be blend with the jet fuel since jartopha oil has a lower freezing point then the jet fuel.
The biodiesel prepared from the jartopha oil can also be mixed with the jet fuel with 50-50 ratio and these neither will nor require any modification in the engine.
Using jatropha biodiesel it is possible to save 3% of the fuel in the engines.
In December 30, 2008 the Air New Zealand flew its test flight successfully with a 50-50 blend with jatropha oil and jet fuel. And in January 2009 Ai New Zealand, Houston based continental Airlines and Japan Air also tested flights with jatropha biodiesel as a jet fuel.
