Abstract: Mixed alcohol formulas can be used as a fuel additive in gasoline, diesel, jet fuel, aviation gasoline, heating oil, bunker oil, coal, petroleum coke or as a neat fuel in and of itself. The mixed alcohols formulations can contain C1-C5 alcohols, or in the alternative, C1-C8 alcohols or higher C1-C10 alcohols in order to boost energy content. The C1-C5 mixed alcohols contain more ethanol than methanol with declining amounts of propanol, butanol and pentanol. C1-C8 mixed alcohols contain the same, with declining amounts of hexanol, heptanol and octanol. C1-C10 mixed alcohols contain the same, with declining amounts of nananol and decanol. Synthetically produced mixed alcohol formulas feature higher octane and energy densities than either MTBE or fermented grain ethanol; more stable Reid Vapor Pressure blending characteristics; and increased soluablizing effects on condensate water. The primary benefits of mixed alcohols are increased combustion efficiencies, reduced emissions profiles and low production costs.
