Abstract
A fuel separation method by which auxiliary fuel is separated from blended gasoline fuel for a flexible fuel vehicle capable of using ethanol-blended gasoline fuel, the method including the following steps (a) and (b): (a) a step in which, when the ethanol concentration is low, the blended gasoline fuel is separated by a polar separating membrane member at a relatively high separation temperature to obtain, at the permeation side of the membrane, a first auxiliary fuel enriched with the aromatic gasoline components and ethanol component, and (b) a step in which, when the ethanol concentration is high, the blended gasoline fuel is separated by a polar separating membrane member at a relatively low second separation temperature to obtain, at the permeation side of the membrane, a second auxiliary fuel enriched with the non-aromatic high-volatile gasoline components.
