EFFECTS OF A NEW BLENDING AGENT ON ETHANOL-GASOLINE FUELS

Successful use of ethanol-gasoline blends as engine fuel alternatives depends on producing a stable homogeneous liquid fuel. It is crucial t o avoid the phase separation phenomenon which occurs due to the hydrop hilic character of alcohols and the solubility behavior of gasoline-al cohol-water three-component system. In this study an industrial byprod uct is introduced as a new blending agent to ethanol-gasoline fuels, a nd its effects on the phase separation problem were investigated on sa mples prepared by blending unleaded gasoline with 5, 10, 15, and 20% ( v/v) azeotropic ethanol, respectively.
