NOVELTY - Method (I) for separating and subsequent processing of fatty acid methyl ester (FAME) fractions of a biodiesel, comprises: (a) providing a biodiesel containing several different FAME fractions mixed together; (b) bringing the biodiesel to a first crystallizing temperature, where when the biodiesel reaches the first crystallizing temperature, a first FAME fraction remains in a non-crystallized, liquid phase while the remaining FAME fractions crystallize; and (c) separating the liquid first FAME fraction from the remaining crystallized FAME fractions.    USE - The method is useful for separating and subsequent processing of fatty acid methyl ester fractions of a biodiesel, which is a Camelina feedstock-based biodiesel (all claimed).    ADVANTAGE - The method provides: the biodiesel that meets the American society for testing and materials D6751 standard; and the FAME fractions having high commercial value outside of their original fuel usage.    DETAILED DESCRIPTION - Method (I) for separating and subsequent processing of fatty acid methyl ester (FAME) fractions of a biodiesel, comprises: (a) providing a biodiesel containing several different FAME fractions mixed together, where the biodiesel is at a first temperature and at the first temperature none of the FAME fractions of the biodiesel have crystallized; (b) bringing the biodiesel to a first crystallizing temperature, where when the biodiesel reaches the first crystallizing temperature, a first FAME fraction remains in a non-crystallized, liquid phase while the remaining FAME fractions crystallize; and (c) separating the liquid first FAME fraction from the remaining crystallized FAME fractions. INDEPENDENT CLAIMS are also included for:    (1) method (II) for separating and subsequently processing of FAME fractions of biodiesel, comprising: (a) as above per se; (b1) cooling the biodiesel from the first temperature to the first crystallization temperature, where a first FAME fraction is a liquid phase while the remaining FAME fractions are crystallized, allowing the first FAME fraction to be separated from the remaining crystallized FAME fractions; and (c1) bringing the temperature of the remaining FAME fractions to a second crystallization temperature in which a second FAME fraction is crystallized while a third FAME fraction is in a liquid phase to allow the third FAME fraction to be separated from the second FAME fraction;    (2) method (III) for separating and subsequently processing of FAME fractions of biodiesel, comprising: (a) and (b1) as above per se; and (c2) subjecting the first FAME fraction to glycerolysis to form alpha -linolenic acid;    (3) method (IV) for separating and subsequently processing of FAME fractions of biodiesel, comprising of the steps: (a) as above per se; (b3) sequentially cooling and heating of a biodiesel to provide for the repeated FAME fraction crystallization and subsequent separation of a first, second, and third FAME fractions of the biodiesel; (c3) subjecting the third FAME fraction to hydrogenation to produce a mono unsaturated FAME; and (d4) performing hydrolysis of the mono-unsaturated FAME to create a first aviation jet fuel composition;    (4) a first jet aviation fuel composition (J1) comprising (in vol.%) 8C (1), 9C FAME (1), 9C (31), 10C FAME (31), 10C (6), 11CFAME (6), 11C (4), 12C FAME (0.5), 13C FAME (0.1), 15C FAME (0.5), 17C FAME (10), 19C FAME (4), 21C FAME (2), 23C FAME (1), and 25C FAME (1); and    (5) a second aviation jet fuel composition (J2) comprising (in vol.%) 8C (1), 9C FAME (1), 9C (28), 10C FAME (28), 10C (20), 11C FAME (20), 12C (1), and 13C FAME (1).
