Abstract: 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.

Abstract: A process of producing high octane hydrocarbons includes the steps of preparing a mixture of substantially ethanol and butane or natural gasoline, or low octane gasoline, the mixture having room temperature and atmospheric pressure, adjusting the pressure of the mixture to a magnitude within the range of 10 to 50 pounds per square inch, adjusting the temperature of the mixture to a magnitude within the range of 100 to 460 degrees Fahrenheit, adjusting the pressure of the mixture to a pressure within the range of 500 to 1000 hydrocarbons pounds per square inch, catalyzing the mixture with a platinum catalyst, lowering the temperature of the mixture to a magnitude within a range of 90 to 190 degrees Fahrenheit, and separating out liquid product and gas from the mixture.

Abstract: A process of producing high octane alcohols includes the steps of preparing a first mixture of substantially ethanol and butane or natural gasoline, the mixture having a certain temperature and a certain pressure, adjusting the certain pressure of the mixture to a magnitude within the range of 10 to 50 pounds per square inch, adjusting the temperature of the mixture to a magnitude within the range of 100 to 350 degrees Fahrenheit, adjusting the pressure of the mixture to a pressure within the range of 500 to 1000 pounds per square inch, catalyzing the mixture with a platinum catalyst, lowering the temperature of the mixture to a magnitude within a range of 90 to 190 degrees Fahrenheit, and separating out liquid product and gas from the mixture. Then a second mixture of said liquid product and methanol is prepared and the process steps are repeated on this second mixture to produce a second product plus gas.
