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.

USDA and DOE select 13 biofuels projects for more than $41M in awards

Green Car Congress

Five projects newly selected will help to replace the need for gasoline and diesel in vehicles. The oils will be hydrotreated to produce diesel and jet fuel. The extracted rubber will be used in tire formulations, and the remaining plant residue will be evaluated for use in biopower and for conversion to jet fuel precursors.
