There is a lot of information, and mis-information, about ethanol, its advantages and disadvantages. I would like this to be a place to openly discuss what these are and how the community feels about it


The Ethanol Reddit

Ethanol - a compound and simple alcohol with the chemical formula C2H5OH. Its formula can be written also as CH3−CH2−OH or C2H5−OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is used as a drug and is the principal type of alcohol found in alcoholic drinks.

Ethanol is naturally produced by the fermentation of sugars by yeasts or via petrochemical processes, and is most commonly considered as a popular recreational drug. It also has medical applications as an antiseptic and disinfectant. The compound is widely used as a chemical solvent, either for scientific chemical testing or in synthesis of other organic compounds, and is a vital substance utilized across many different kinds of manufacturing industries. Ethanol is also used as a clean energy burning fuel source.

Been using ethanol 40% to 60%petrol in my 09 Lexus rx 200 without a converter.

It's been about a year and no problems so far. Should I be expecting any? When the price of petrol in France shot up I noticed more people at the ethanol pump so I thought, why not? What I'm saving at the pump is already more than the car is worth. I do love this car though, and really would rather not kill it. What say you?

Specs - 95% & 99%

Can anybody provide spec sheets for 95% and 99% ethanol? This is the ethanol used to make E-10 gas.

Hello this is an email I sent to an laboratory supply company. Redditor's often have better ideas anyway so I am asking here too!

Hello, I am a TTB Permit holder for small fuel ethanol production. I can send a copy of my permit or you can check my name with the TTB.

The trouble is, of course, is that no matter how perfect my process is, I can't get ethanol more concentrated than 97.2% (volume) Personally I have only been able to produce a small sample at anything close to that out of 90 gallons. I am not kidding, maybe a half gallon approaches 95% or 96%. I have a great many notes of all the things I would like to try to improve the process.

My problem is that I have given up because I didn't know when I started, that I would be incapable of producing better than 97.2%. This is still too much water unless I mix about a half a cup in a full tank of gas.

I have given up for years but I recently saw that large ethanol fuel plants use vacuum to pull EtOH through a desiccator.

I would love a list of product to try that might replicate this. Low pressure, no pressure, doesn't matter, I won't be fussy if it doesn't work. I genuinely loved this hobby and I was really good at it. I just want something to try again and learn more about a 3 angstrom sieve, which is what I will need eventually but that is far down the line.

If you will help me with a few products that might work, the processes or additional equipment needed to operate them, please try to stay at 110v but if not I can do 220v it just means running a fat cable through part of my home.

Thanks!

Ethanol buyers

I’m doing a school project on ethanol. I’m wondering if you guys know if there are any companies or people who would buy pure ethanol in California?

how to move forward with production and setting up?

Who is Correct - EPA or the Ethanol Industry?

There is only one entity who can be correct. The Ethanol Industry promotes ethanol as a cleaner burning fuel, but EPA continues to put out information and models that show ethanol makes air quality worse. EPAs recently released Third Triennial Report to Congress which reports that for every 1 percent increase in ethanol use, there is a 1 percent increase in VOC’s, NOx, and PM2.5. EPA also models that ethanol increases ozone in much of the US compared to no ethanol usage.

EPA’s supporting studies for tailpipe emissions use test fuels manipulated by the American Petroleum Institute (API). EPA’s position regarding ethanol raising tailpipe emissions is that ethanol’s cooling effect impacts gasoline’s ability to atomize just prior to combustion and makes gasolines emissions increase. For vehicle evaporative emissions, EPA also states that ethanol makes permeation worse but ignores how it is actually aromatics that increase permeation. Again, manipulated fuel studies funded by API.

The Ethanol Industry makes the claim that ethanol improves air quality when simply adding ethanol to gasoline for test purposes and that is a consistent trend for those types of studies.

What EPA omits from their modeling is that ethanol in gasoline today (E10), displaces the need for nearly 8 to 9 billion gasoline of toxic aromatics annually in the US gasoline market. That is mainly due to ethanol’s high octane which is higher than any option available at an oil refinery today.

Leave your vote below in the comment section. Is EPA correct or is the Ethanol Industry? Both parties can’t be right on this issue.
