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.

Researchers from the University of Wisconsin Madison and ExxonMobil Research and Engineering have devised a two-stage process by which an alcohol such as ethanol or 1-butanol can be converted with high yields into distillate-range ethers and olefins by combining Guerbet coupling (the coupling of two alcohol molecules) and intermolecular dehydration.

Much effort has recently gone into pathways to produce hydrocarbons with extended carbon chains by the hydrogenation of carbohydrate derivatives. These efforts include the aqueous phase reforming (APR) process, by which sugars are converted to alkanes by hydrogenation with noble metals as catalysts.

Generally speaking, noted AVL researchers in a paper on the problem (Johnson & Hunter 2012), military-grade jet fuels have higher energy content on a mass basis (as a result of the higher hydrogen to carbon ratio), but lower energy density on a volume basis.

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.
