FUEL ADDITIVE AND METHOD THEREFOR

摘要

The invention provides a fuel additive composition including from about 85 to about 99% by volume C1-C4 alcohol having a first blending octane number and from about 1.0 to about 15% by volume ether compound selected from the group consisting of dialkoxyalkanes, alkoxyalcohols, trialkoxyalkanes, dialkoxycycloalkanes and aryl alkyl diethers having a second blending octane number and a boiling point in the gasoline boiling range. The resulting composition has a third blending octane number which is substantially greater than a linear addition of the first and second blending octane numbers of the components of the mixture. In the composition, the second blending octane number is substantially lower than the first blending octane number. The fuel additive composition significantly increases the octane number of a gasoline fuel without detrimentally affecting the environment.
