ENVIRONMENTALLY FRIENDLY TERNARY TRANSPORTATION FLEX-FUEL OF GASOLINE, METHANOL AND BIOETHANOL

摘要

An efficient and economic ternary flex-fuel mixture that includes at least 10% gasoline, at least 10% bioethanol and at least 45% methanol, with the amount of gasoline, bioethanol and methanol totaling 100%, wherein the flex-fuel mixture has an octane rating of at least 90 and remains homogeneous in the presence of up to 10% water therein. Preferred flex-fuel mixtures include 10-15 to 30% gasoline, 50 to 75-80% methanol, and 10 to 25% of bioethanol and having an octane rating of 90 to 98. Also, methods of making these flex-fuel mixtures and to improvements in methods for preparing a flex-fuel mixture of gasoline and bioethanol by adding methanol in an amount sufficient to enable the mixture to remain homogeneous in the presence of up to 10% water to thus allow handling, transportation, dispensing and use of the mixture in the same manner as conventional gasoline fuels.
