20090062559 | METHOD FOR PRODUCTION OF BIOFUEL - Alkyl esters boiling largely within the specification range for jet fuel may be made from triglycerides without a water-washing step, by centrifugation in a timely manner and at a sufficiently high time/G-force/distance product so as to bring about separation of a transitory second phase containing the residual catalyst. The esters or fractions thereof may be combined with jet or diesel fuels to lower the freezing and cloud points respectively. | 03-05-2009 |
