Development of technology for producing bio-jet fuel from several feedstocks

To reduce the emission of greenhouse gases and broade the raw material sources of jet fuel, many countries have accelerated the development of bio-jet fuel. The technology for producing bio-jet fuel by hydrotreating vegetable oils or animal fat has been developed by SINOPEC, which contains different processing routes to produce bio-jet fuel and bio-diesel to meet the market demands, such as the route of producing bio-jet fuel maximally, and the route of producing bio-jet fuel and bio-diesel at one time. Relative to vegetable oil or animal fat, the final yield of bio-jet fuel with freezing point lower than -48 ℃ can reach to 35%-45%, the yield of diesel is 7%-11%, and the yield of naphtha is 23%-29%. The bio-jet fuel product fitting for the standard of ASTM D7566-11 has been produced by SINOPEC in an industrial unit, which was successful in the flight-test.
