Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.

Fuels can include gasoline blends, and alcohol blended hydrocarbon fuel grades. Ethanol blended hydrocarbon fuels can include higher ethanol blends (e.g. E80, E85), and neat ethanol (E99).

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

Of these 10 blendstocks, six were assessed to have the fewest significant practical barriers to adoption which include alcohols and an olefine (alkene): di-isobutylene, ethanol, a fusel alcohol blend, isobutanol, n-propanol, and isopropanol.
