Study shows branched ketone biofuels derived from alcohols have potential for use in aviation fuel blends 25 December 2015 Researchers at the University of Bath (UK) have demonstrated that branched ketone biofuels produced from the alkylation of isoamyl alcohol and isobutanol with acetone have the potential to be used as blending agents with Jet A-1 fuel. A paper on their work is published in the ACS journal Energy & Fuels . Although the technology to produce cellulosic ethanol is becoming established, ethanol’s low energy density and high affinity for water have led to the development of higher energy density alochol alternatives such as n-butanol, isoamyl alcohol, and isobutanol. However, the water affinity, low flash point, and low boiling point still make these compounds unsuitable for aviation use without further upgrading. Alkylation (the transfer of an alkyl group—a...
