Take biomass-derived acetone—common nail polish remover—use light to upgrade it to higher-mass hydrocarbons, and, voila, you have a domestically generated product that can be blended with conventional jet fuel to fly while providing environmental benefits, creating domestic jobs, securing the nation’s global leadership in bioenergy technologies, and improving U.S. energy security.

“This process allows us to transform a natural product into a fuel additive, improving the performance of petroleum-based jet fuel,” said Courtney Ford Ryan, a postdoctoral fellow at Los Alamos National Laboratory and lead author of a paper out in preprint form in the journal Sustainable Energy and Fuels.
“We converted bio-derived acetone to isophorone and then used a UV lamp to convert it to a cyclobutane, a type of hydrocarbon with high energy density for fuels applications,” Ryan said.
There are many challenges in using acetone for fuels applications, the paper’s authors note. Its volatility precludes its direct use as a fuel, and it requires chemical upgrading to be suitable for introduction into the fuel supply, as acetone has a nasty habit of dissolving engine parts and O-rings. So by upgrading the initial product to a cyclobutane, a potentially safer and more energy-dense fuel is created, while reducing the hydrogen input required for upgrading a bio-derived feedstock.
