I am interested in identifying suitable vegetable oils or other biofuel alternatives which can be mixed with ethanol and perhaps cut by kerosene to power gas turbine engines.

The real problem which faces the aviation industry is that in order to get certification the biofuel must not solidify or gel above -40 celsius.

Some research has been done with Soya oils but, apart from that what oils can members suggest with perhaps better properties than Soya oil please ?

By that I guess I mean higher viscosity ?

Has anybody got any thoughts about olive oil, corn oil, sunflower oils, or anything else promising ?

Thing is if we make jet fuel from matter which is grown, then in the process of growing carbon is taken from the atmosphere and when burned again it does not create a net increase in CO2 levels.
