Biogasoline

Biogasoline are biohydrocarbons with between 5 and 12 carbon atoms per molecule, mainly hexane.

These biogasolines can be used in pure state (100% biogasoline or BG100) in any conventional gasoline engine (as happens with biobutanol), and can be distributed in the same fueling infrastructure, as the properties match traditional gasoline from petroleum.^[1] Heptanone is not really biogasoline and requires a small percentage of octane booster to match gasoline. Ethanol fuel (E85) requires a special engine and has lower combustion energy and corresponding fuel economy.^[2]

Biogasoline is different from biobutanol and Ethanol, as they are bioalcohols and not bio-hydrocarbons.
