The fuel is produced through fermentation of corn feedstock and the process is nearly identical to fuel ethanol production from corn. The first demonstration-scale biobutanol plants were retrofits of existing corn ethanol plants. ![]() It is anticipated that biobutanol would be distributed by tanker truck and rail, with the potential for transportation in pipelines upon research demonstrating its safety. Underwriters Laboratories announced in 2013 that equipment certified under testing subject 87A (for blends above E10) could also retain certification if used with biobutanol. ![]() Oak Ridge National Laboratory has researched the compatibility of fueling equipment materials with biobutanol and found that equipment compatible with ethanol blends is also compatible with biobutanol. The EPA-approved 16% biobutanol level was determined based on the assumption that no other oxygenates (e.g., ethanol) are included in the fuel blend. It is important to ensure that biobutanol blended with gasoline does not result in an oxygen content exceeding the EPA limit of 3.7%. Butanol has an ASTM D7862 fuel quality standard for blends up to 12.5% with gasoline.Īs of June 2018, the EPA approved up to 16% biobutanol blends. Environmental Protection Agency (EPA), a 16% biobutanol blend is a legal fuel equivalent to E10 (10% ethanol, 90% gasoline). Additionally, under a waiver granted by the U.S. Two Clean Air Act provisions allow for blending of up to 12.5% biobutanol by volume with gasoline. While there are four isomers of butanol, the most active commercialization work centers on isobutanol for blending with gasoline. Under the Renewable Fuel Standard, corn grain butanol meets the renewable fuel 20% greenhouse gas emission reduction threshold. The benefits of biobutanol, when compared with ethanol, are that biobutanol is immiscible in water, has a higher energy content, and has a lower Reid vapor pressure. The term biobutanol refers to butanol made from biomass feedstocks. Butanol, a 4-carbon alcohol (butyl alcohol), is produced from the same feedstocks as ethanol, including corn grain and other biomass.
