| 20120174473 | METHODOLOGY OF POST-TRANSESTERIFICATION PROCESSING OF BIODIESEL RESULTING IN HIGH PURITY FAME FRACTIONS AND NEW FUELS - A methodology for separation and subsequent handling of FAME fractions of biodiesel, comprising of the steps, providing a biodiesel containing several different FAME fractions mixed together, the biodiesel being at a first temperature wherein at the first temperature none of the FAME fractions of the biodiesel have crystallized; bringing the biodiesel to a first crystallizing temperature, wherein 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 separating the liquid first FAME fraction from the remaining crystallized FAME fractions. | 07-12-2012 |
