  • E100
  • By December 2011 Brazil had a fleet of 14.8 million flex-fuel automobiles and light trucks and 1.5 million flex-fuel motorcycles that regularly use neat ethanol fuel (known as E100). (wikipedia.org)
  • The ethanol-powered "flex" vehicles, as they are popularly known, are manufactured to tolerate hydrated ethanol (E100), an azeotrope composed of 95.6% ethanol and 4.4% water. (wikipedia.org)
  • biofuels
  • If it seems like you've read a variation of the above headline before you're not wrong, and as much as anything it's a sign of the rock road cellulosic ethanol and biofuels in general have had in the past few years. (treehugger.com)
  • Absence of production of cellulosic ethanol in the quantities required by the regulation was the basis of a United States Court of Appeals for the District of Columbia decision announced January 25, 2013, voiding a requirement imposed on car and truck fuel producers in the United States by the Environmental Protection Agency requiring addition of cellulosic biofuels to their products. (wikipedia.org)
  • aliphatic
  • Members of this enzyme family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. (wikipedia.org)
  • blend
  • Ethanol fuel production peaked during World War II and, as German submarine attacks threatened oil supplies, the mandatory blend became as high as 50% in 1943. (wikipedia.org)
  • production
  • An ethanol production mandate could be in conflict with efforts to reduce the Gulf Coast dead zone. (treehugger.com)
  • President Trump promised to be a bio-fuels booster when he was running for office, but EPA Administrator Scott Pruitt has proposed lowering next year's federally-mandated production levels for biodiesel and cellulosic ethanol. (radioiowa.com)
  • The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat. (wikipedia.org)
  • Concerns about its production and use relate to increased food prices due to the large amount of arable land required for crops, as well as the energy and pollution balance of the whole cycle of ethanol production, especially from corn. (wikipedia.org)
  • Recent developments with cellulosic ethanol production and commercialization may allay some of these concerns. (wikipedia.org)
  • The refurbished facility became fully operational with the production of the first batch of ethanol in June 2010. (wikipedia.org)
  • The focus in recent years has been on the improvement of the material, energy and life cycle assessment of the production of ethanol. (wikipedia.org)
  • Construction of the facility took place during 2006 with ethanol production beginning in February 2007. (wikipedia.org)
  • Ethanol Production Using Waste Heat" (PDF). (wikipedia.org)
  • C2H5OH
  • Deuterated ethanol (C2D5OD) is a form (called an isotopologue) of ethanol (C2H5OH) in which the hydrogen atom ("H") is replaced with deuterium (heavy hydrogen) isotope ("D"). Deuterated ethanol is an uncommon solvent used in NMR spectroscopy. (wikipedia.org)
  • ethylene
  • Ethanol may be administered as an antidote to methanol and ethylene glycol poisoning. (wikipedia.org)
  • Ethanol may also be produced industrially from ethylene by hydration of the double bond in the presence of catalysts and high temperature. (wikipedia.org)
  • fossil fuels
  • Since most U.S. ethanol is produced from corn and the required electricity from many distilleries comes mainly from coal plants, there has been considerable debate on the sustainability of corn-based bio-ethanol in replacing fossil fuels. (wikipedia.org)
  • greenhouse
  • The Congressional Budget Office has now weighed in on ethanol mandates so I guess now it makes it official: they drive up food prices and do nothing for greenhouse gas emissions. (globalwarming.org)
  • CBO also noted that pushing for ethanol could actually increase greenhouse gas emissions, with deforestation being one reason among many for that consequence. (globalwarming.org)
  • aqueous
  • Ethanol precipitation is a method used to purify and/or concentrate RNA, DNA, and polysaccharides such as pectin and xyloglucan from aqueous solutions by adding ethanol as an antisolvent. (wikipedia.org)
  • America
  • Today, Reynolds said reducing the federal volume requirements for ethanol and biodiesel next year will send commodity prices even lower and "devastate" rural America. (radioiowa.com)
  • enzymes
  • In fact, certain amino acid sequences in the enzymes used to oxidize ethanol are conserved all the way back to single cell bacteria. (wikipedia.org)
  • In human embryos and fetuses, ethanol is not metabolized via this mechanism as ADH enzymes are not yet expressed to any significant quantity in human fetal liver (the induction of ADH only starts after birth, and requires years to reach adult levels). (wikipedia.org)
  • The facility has been designed and engineered to process 40 tons of wheat straw per day into ethanol using enzymes made in an adjacent enzyme manufacturing facility. (wikipedia.org)
  • molecules
  • It is also important to note that step 1 on this reaction is endothermic, requiring 47.2 kJ/mol of alcohol, or about 3 molecules of ATP (adenosine triphosphate) per molecule of ethanol. (wikipedia.org)
  • mixture
  • Distributed by Statoil, the Bio95 2G mixture uses ethanol derived from wheat straw collected on Danish fields after harvest and produced by Inbicon (a div. of DONG Energy), using enzyme technology from Novozymes. (wikipedia.org)
  • sugar
  • Ethanol producers in the state of São Paulo established a research and technology transfer center that has been effective in improving sugar cane and ethanol yields. (wikipedia.org)
  • water
  • Ethanol is much less polar than water, with a dielectric constant of 24.3 (at 25 °C). This means that adding ethanol to solution disrupts the screening of charges by water. (wikipedia.org)
  • As a result of the increasing use of ethanol, together with the exploitation of domestic deep water oil sources, Brazil reached in 2006 a volumetric self-sufficiency in oil supply, but is not effectively self-sufficient, since most of its locally extracted oil is heavy. (wikipedia.org)
  • made
  • American Ethanol is a collaborative-effort marketing campaign intended to increase awareness of the reliability, performance capabilities and affordability of American-made E15 ethanol. (wikipedia.org)
  • The racing fuel is made up of 15 percent American-made, corn-based ethanol. (wikipedia.org)
