What is a reformulated gasoline?
Reformulated Gasoline (RFG) is “clean-buming” gasoline that will significantly improve air quality by reducing emissions from all gasoline-burning motor vehicles and engines.
What is in reformulated fuel?
Today, over 30 percent of the gasoline sold in the United States is RFG. The EPA requires the new reformulated gasoline to have an oxygen content of just over 2 percent to help the gasoline burn cleaner. The two primary oxygenate additives are ethanol (corn alcohol) and methyl tertiary butyl ether (MTBE).
What is oxygenated and reformulated gasolines?
Oxygenated gasoline includes all finished motor gasoline, other than reformulated gasoline, having oxygen content of 2.0 percent or higher by weight. Gasohol containing a minimum 5.7 percent ethanol by volume is included in oxygenated gasoline.
What are the types of ethanol blended gasoline?
There are three general categories of ethanol-gasoline blends: E10, E15, and E85. E10 is gasoline with 10% ethanol content. E15 is gasoline with 15% ethanol content, and E85 is a fuel that may contain up to 85% fuel ethanol.
Does 10 ethanol reduce gas mileage?
The math carries to E10, which has up to 10 percent ethanol. A gallon of E10 has 96.7 percent of the energy in one gallon of gasoline, according to the DOE’s Alternative Fuels Data Center. That means E10 gas fractionally lowers real-world gas mileage.
What is Cbob gas?
Glossary Terms » CBOB (Conventional Blendstock for Oxygenate Blending) Conventional gasoline blendstock intended for blending with oxygenates downstream of the refinery where it was produced. CBOB must become conventional gasoline after blending with oxygenates.
Does reformulated gasoline contain ethanol?
Ethanol is the oxygenate most widely used in reformulated gasoline.
What is E25 gas?
E20 contains 20% ethanol and 80% gasoline, while E25 contains 25% ethanol. These blends have been widely used in Brazil since the late 1970s. As a response to the 1973 oil crisis, the Brazilian government made mandatory the blend of ethanol fuel with gasoline, fluctuating between 10% to 22% from 1976 until 1992.
What is re-reformulated gasoline?
Reformulated gasoline (RFG) is gasoline blended to burn more cleanly than conventional gasoline and to reduce smog-forming and toxic pollutants in the air we breathe.
Does reformulated gasoline produce less pollution?
Reformulated gasoline produces between 5 and 17 percent less pollution than conventional gasoline. Reformulated gasoline is created by using smaller amounts of benzene than in conventional gases. Safeopedia Explains Reformulated Gasoline A reformulated gasoline program was mandated by the US Congress in the 1990 Clean Air Act amendments.
Is reformulated gasoline mandatory in some cities?
In cities with high smog levels, providing a reformulated gasoline option is mandatory, while in other cities it is optional. Approximately 30 percent of the gasoline currently sold in the United States is reformulated.
Can we produce hydrogen from reformulated gasoline in the USA?
However, the reformulated gasoline program introduced in the USA in the 90s demands for a decline in reforming capacities, which considerably reduces the potential for hydrogen production at refinery plants [2].
