Researchers at the University of Wisconsin, led by Dr. James Dumesic, have developed a process to convert aqueous solutions of ?-valerolactone Not requiring hydrogen or precious metal catalysts could contribute to a lower cost for a commercial-scale version of the process than some other renewable hydrocarbon fuel technologies.

Researchers at the University of Wisconsin-Madison have demonstrated that it is possible to achieve good yields of renewable hydrocarbons in the molecular weight range suitable for jet and diesel fuel applications through the processing of C 9 alkenes produced from biomass-derived ?-valerolactone Source: Alonso et al.

Unlike ethanol, GVL will not form an azeotrope with water, thus eliminating the need for azeotropic distillation or molecular sieve methods in the final purification steps. The additive shifts the distillation curve for diesel fuel to lower temperatures, with most of the additive removed from the mixture by the 40% distillate volume fraction.
