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.
