Engineers develop higher-energy liquid-transportation fuel from sugar

‘Reporting in the June 21 issue of the journal Nature, University of Wisconsin-Madison chemical and biological engineering Professor James Dumesic and his research team describe a two-stage process for turning biomass-derived sugar into 2,5-dimethylfuran (DMF), a liquid transportation fuel with 40 percent greater energy density than ethanol.

The prospects of diminishing oil reserves and the threat of global warming caused by releasing otherwise trapped carbon into the atmosphere have researchers searching for a sustainable, carbon-neutral fuel to reduce global reliance on fossil fuels. By chemically engineering sugar through a series of steps involving acid and copper catalysts, salt and butanol as a solvent, UW-Madison researchers created a path to just such a fuel.’
