Pruitt Raises Idea of Higher Levels of Ethanol-Free Gasoline

Submitted by on July 7, 2017 – 2:51 pmNo Comment

by Chris Clayton (DTN The Progressive Farmer)  … (EPA Administrator Scott ) Pruitt also noted that EPA will be “assessing higher levels of ethanol-free gasoline.”

Ethanol-free gasoline translates into higher volumes of aromatic chemicals to raise the octane levels of gasoline. The focus on higher levels of ethanol-free gasoline also runs completely counter to the push by the biofuels industry to increase blend levels to E15 or even E30.

Bob Dinneen, president of the Renewable Fuels Association, touched on that octane connection in a column Thursday, citing that “RFA continues to believe biofuel and petroleum fuel producers should be working together to introduce liquid fuel formulations that offer optimal engine performance, superior fuel economy, reduced GHG and criteria emissions, and lower prices for consumers. That means transitioning to an ethanol-based high octane, low carbon fuel blend like E25 or E30 in the long term.”

Dinneen also pointed to a quote from Tom Kloza, founder of the Oil Price Information Service, at a recent energy conference, citing that “we’ll need more octane for the US gasoline pool if (liquid) fossil fuel is to remain dominant.”

A gallon of 91-octane gasoline with no ethanol will contain aromatic compounds such as benzene, toluene and xylene. These are toxic chemicals coming out of the tailpipe just so the petroleum refiners can boost octane levels without having to use higher ethanol blends.

So why would EPA be looking at “higher levels of ethanol-free gasoline” when the petroleum industry is acknowledging the need to move to higher octane levels? That seems to go against the mission of EPA, which is cleaner air. Higher blends of ethanol can help reduce aromatics, which is a focus of groups such as the Urban Air Initiative, and the push from other groups to increase ethanol blend levels at the pump.  READ MORE
