Industry Tests Show Bio-Derived Synthetic Paraffinic Kerosene Performs as Well as Petroleum Jet Fuel; Aviation Partners Push for Approval for Use

Green Car Congress

The Bio-SPK process converts bio-derived oils (triglycerides and free fatty acids) to Bio-SPKs. The removal of the oxygen atoms raises the heat of combustion of the fuel and the removal of the olefins increases the thermal and oxidative stability of the fuel. IATA 2008 Report on Alternative Fuels.
