This article is about Butanol from biomass used as a platform chemical and fuel. For other alcohols used as fuels, see Alcohol fuel.
Butanol may be used as a fuel in an internal combustion engine. It is more similar to gasoline than it is to ethanol. A C4-hydrocarbon, butanol is a drop-in fuel and thus works in vehicles designed for use with gasoline without modification.[1]
Both n-butanol and isobutanol have been studied as possible fuels. Both can be produced from biomass (as "biobutanol"[2][3][4] ) as well as from fossil fuels (as "petrobutanol"[5]). The chemical properties depend on the isomer (n-butanol or isobutanol), not on the production method.
