Dupont has been pushing Butanol for years. You don’t have to worry about E15 or E85. You just pour this stuff in the tank and it works like gasoline. Supposedly gets better mileage than gasoline.

What Is Butanol?

Butanol is a four carbon alcohol. It has double the amount of carbon of ethanol, which equates to a 25 percent increase in harvestable energy (Btu’s).

Butanol is produced by fermentation, from corn, grass, leaves, agricultural waste and other biomass.

Butanol is safer to handle with a Reid Value of 0.33 psi, which is a measure of a fluid’s rate of evaporation when compared to gasoline at 4.5 and ethanol at 2.0 psi.

Butanol is an alcohol that can be but does not have to be blended with fossil fuels.

Butanol when consumed in an internal combustion engine yields no SOX, NOX or carbon monoxide all environmentally harmful byproducts of combustion. CO2 is the combustion byproduct of butanol, and is considered environmentally ‘green’.

Butanol is far less corrosive than ethanol and can be shipped and distributed through existing pipelines and filling stations.

Butanol solves the safety problems associated with the infrastructure of the hydrogen supply. Reformed butanol has four more hydrogen atoms than ethanol, resulting in a higher energy output and is used as a fuel cell fuel.

Butanol is an industrial commodity, with a 370 million gallons per year market with a selling price of $3.75 per gallon.

Hydrogen generated during the butanol fermentation process is easily recovered, increasing the energy yield of a bushel of corn by an additional 18 percent over the energy yield of ethanol produced from the same quantity of corn.

All true, BUT...I have been concerned about ethanol in fuel because of other possible chemicals formed by its partial combustion and its passing through catalytic converters. The converters are used to reduce the oxides of nitrogen and sulfur in order to lower levels of "smog". However, we also know that the metals used in the converters can also, under certain circumstances, cause OXIDATION of chemicals passing over them.

Thus, from ethanol we might get acetaldehyde (possibly formed via ketene), a highly reactive and biologically harmful material. Only 10% ethanol is now routinely added to gasoline; if we decide to burn 100% n-butanol, would we have to deal with the obnoxious butyraldehyde that may be produced?
