Physicochemical Properties of Butanol-Gasoline Blends
Department of Petroleum Technology and Alternative Fuels, Institute of Chemical Technology, Prague
Biobutanol can be used as a biofuel in the same manner as bioethanol in spark-ignition engines. The article deals with the relevant properties of biobutanol-gasoline blend important for fuels such as density, viscosity, water solubility, vapour pressure and oxidation stability. Gasoline blends with 10 v/v % of biobutanol show properties close to those of ordinary gasoline, therefore biobutanol could be a promising alternative to ethanol currently used in automotive gasoline.
