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. An apparatus for producing high octane alcohols includes a starting tank for retaining a mixture of substantially ethanol and butane or natural gasoline, or low octane gasoline, a heat exchanger for raising the temperature of the mixture, a first high pressure conduit extending from the starting tank to the heat exchanger, a catalyzing chamber, second and third high pressure conduits extending from the heat exchanger to the catalyzing chamber, a nozzle interconnecting the second and third high pressure conduits, high pressure pumps for extracting the heated mixture from the heat exchanger and delivering the mixture to the catalyzing chamber through the second and third high pressure conduits, and a separator for precipitating liquid product out of the mixture.
