Study of Vapor Pressures of Gasoline-Alcohol Blends Finds That Dual-Alcohol Blends Can Result in RVPs Identical to That of Gasoline

Green Car Congress

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. Evaporative emissions from gasoline—volatile organic compounds (VOCs)—are precursors to the formation of tropospheric ozone and contribute to ground-level ozone. Credit: ACS, Andersen et al.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Since the 1973 oil crisis, a plethora of books and instruction manuals have been published in the US on the subject of how to build small stills to produce inexpensive 192-proof alcohol (hydrous ethanol) to be used to blend with gasoline in motor vehicles. Until fairly recently, these US motor vehicles were non-FFVs.
