The APR technology was discovered at the University of Wisconsin in 2001 by Virent’s co-founder and chief technology officer, Dr. Randy Cortright. Some of the reactions in the APR step include: reforming to generate hydrogen; dehydrogenation of alcohols/hydrogenation of carbonyls; deoxygenation reactions; hydrogenolysis; and.

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. The presence of up to 2.5% (v/v) of γ-valerolactone in diesel fuel does not appear to affect the volatility to any great extent. —Bruno et al.

Valeric biofuels are produced by acid hydrolysis of lignocellulose to levulinic acid, followed by its hydrogenation to GVL, and its hydrogenation to valeric acid and subsequent esterification. GVL is produced by the hydrogenation of levulinic acid derived by the simple acid hydrolysis of lignocellulosic feedstock.
