Ethanol resources on the Web

The StillMaker: designed for booze, but it makes 190-proof alcohol.

Some of the resources here have more to do with drinking than driving, but the homebrew hooch specialists make good ethanol of high purity, though generally in smaller quantities, and some of the most knowledgeable people on the subject and best resources on distilling are found among the homebrewers.

Proof and percent: The "proof" measure is double the percentage volume of pure alcohol. Thus 100-proof spirit contains 50% alcohol by volume, 200-proof is 100% pure.

The Biofuel mailing list run by Journey to Forever is an information-sharing resource for anyone who is making their own fuel or has an interest in biofuels or related issues.

All aspects of biofuels and their use are covered -- biodiesel, ethanol, other alternative fuels, related technologies and issues, energy issues, environment, sustainability and more.

The list has a large and varied global membership and has been at the forefront of small-scale biofuels development for more than six years.

Comment from a member: "I just want to say how important what you all are doing here is (I'm just an interested bystander). Closed-system fuel production, on a local or small regional scale, tied to local resources, using accessible technologies, and dependent on entrepreneurial innovation combined with open-source information exchange--it's AWESOME. Keep up the good work everyone, before the planet fries."

Another comment: "Some of the brightest biofuel brains in the world."

And another: "Your list contains some of the best information I have found on the Internet. The archives are great and that is where I spend most of my time acquiring knowledge. This information I believe vitally important NOW and am very happy it is here. Our future may just depend upon it. Now that is important."

More:

• "I came to the list strictly interested in getting my biodiesel project off the ground. Following the various postings I have discovered that I see the world as if from the bottom of a well. The view is expanding ever so slightly, ever so slowly. Thanks to all."
  
  
• "The Biofuel list has awakened me to many ways I can directly help make a difference. The knowledge I have gained from reading the list in a few short months has encouraged me to try again."
  
  
• "I benefit very much personally from the list, and I have yet to make one drop of biofuel! But the insights that I get from the list are amazing."
  
  
• "I like the global view. It's good to have your beliefs challenged."

"Making Ethanol from Sugar Cane in Brazil" by Isaias de Carvalho Macedo, from "Energy As An Instrument for Socio-Economic Development", UNDP, 1995 -- Case study of the "large-scale" production of fuel ethanol from sugar cane in Brazil from the perspective of job creation. Ethanol production has provided nearly 700,000 jobs in Brazil, 75% of them direct jobs. The so-called "large scale" biomass conversion to energy is in fact a large collection of small-scale systems; in the Brazilian case, this corresponds to the scale of agriculture generally... The ethanol programme has been an important factor in creating job opportunities, in both more and less developed regions of Brazil. In some regions, it has been remarkable at evolving from lower to higher-quality jobs, reducing seasonal unemployment, increasing wages and social benefits, and introducing new technologies in a timely way.

Brazil's National Alcohol Program: The objective of the National Alcohol Program (PROALCOOL), established in 1975, was to use ethanol as a fuel substitute for gasoline and to increase ethanol production for industrial uses. By 1985, some US$6.5 billion had been invested in the production of 13 billion gallons (50 billion liters) of ethanol, some 500,000 jobs had been created, 2.5 million vehicles were running on pure ethanol, and all the gasoline at filling stations had an admixture of 20 percent ethanol. Brazil now has technology and equipment capable of maintaining a four billion gallon (16 billion liter) annual output and of exporting the related technology, equipment, and services. By dramatically reducing the level of carbor monoxide released by motor vehicles, PROALCOOL is contributing to Brazil's efforts towards protecting the environment. See:

Ethanol from cellulose

Particularly in the US, the prospect of producing ethanol from cellulose has been attracting much attention in the increasingly desperate search for "alternatives" to the current use (overuse) of fossil-fuels. (See "How much fuel can we grow? How much land will it take?")

Here are some facts:

• Ethanol from cellulose is not something that yet exists outside a few laboratories and pilot projects, and don't hold your breath waiting for it -- it's been "just around the corner" for years, and that's where it remains, despite the many promises made by companies involved in developing the technology.
  
  
• Ethanol from cellulose is not something you're going to be able to produce in your backyard -- these will be big, centralised, expensive, industrial-scale projects which have no place in Appropriate Technology solutions.
  
  
• It is a delusion that there is an endless supply of agricultural "wastes" that can be turned into fuel via ethanol from cellulose conversion or any other process. A proportion of agricultural wastes, like all organic wastes, have to be recycled to the soil to maintain soil fertility levels; the less efficiently this is done, the more will have to be returned. So-called alternative methods of fertility maintenance, eg chemical "fertilisers", do not work well, create horrendous environmental problems, are themselves heavily dependent on fossil-fuel inputs, and, essentially, have no future, let alone as part of a scheme to provide an alternative to fossil-fuel overuse.

With all that in mind, read on:

Ethanol biodiesel

Making ethyl-esters biodiesel using ethanol is a tricky process, not as simple as making methyl esters with methanol. But it can be done -- the following technical papers are available online in our Biofuels Library, and there's sound advice below from a master home-brewer who routinely makes his own ethyl-esters biodiesel.

Optimization of a Batch Type Ethyl Ester Process -- a recipe for biodiesel from ethanol (which you can make yourself), instead of methanol (which is toxic, fossil-fuel derived, and you can't make it yourself).

Making and Testing a Biodiesel Fuel Made From Ethanol and Waste French-Fry Oil by Charles L. Peterson, Daryl Reece, Brian Hammond, Joseph C. Thompson, Sidney Beck, University of Idaho, Idaho, USA (Acrobat file, 2.4Mb)

Biofuels mailing list member Ken Provost, who has much experience making ethyl esters, sent us the following tips&tricks sheet.

Ethanol-based Biodiesel

1. Get plenty of experience making biodiesel with methanol before you try it with ethanol. Get comfortable titrating your oil for FFAs (free fatty acids); you’ll need to do that when you use ethanol.

2. Try to find a source of KOH (potassium hydroxide) to use instead of lye with ethanol. Lye (NaOH, sodium hydroxide) will work, but it dissolves VERY slowly in ethanol. You'll need to use more of either one -- 7g per liter of clean oil with NaOH, 10g per liter of clean oil with KOH. More as required per your titration level.

3. Your ethanol will have to be EXTREMELY dry. 199-proof or higher. "Absolute" ethanol. Any more than one half of one percent water can kill the reaction. Denaturants like methanol, isopropyl alcohol, MIBK, etc., are fine. But no water. Ethanol that dry is difficult to find cheap, especially in the US. If you want to try to make it yourself, you'll need molecular sieve, quicklime, or something else to do a "chemical" drying. Distillation alone can't get the water under 5% -- still way too much. (See below -- Anhydrous ethanol)

4. If you're interested in ethanol for environmental reasons, be careful. Even if you find anhydrous ethanol, it may come from fossil fuel. The denatured alcohols used by painters, or in other industrial applications, may be anhydrous but still derived from petroleum. In fact, since fermentation uses water, it's cheaper to make 200-proof starting with petroleum. The only way to know is to call the original manufacturer of the formula. Ask if the ethanol is "synthetic" or "fermentation". One type of denatured anhydrous ethanol that is almost always fermented is "fuel-grade", which is 199-proof denatured with gasoline. It's what they add to gasoline to make gasohol.

5. Your oil will also have to be EXTREMELY dry. Heat the oil to 120 deg C (248 deg F) and hold it there until you can turn off the flame and see the bubbling stop almost immediately. You might want to throw in some clumping cat litter (bentonite clay) and/or silica gel to scarf up any remaining water, let it settle half a day, and take the oil off the top. Sometimes that's still not dry enough. Remember -- any more than 0.5% water can kill the reaction.

6. Your oil will have to be fairly low in FFAs. You'll want to do a titration on every batch to make sure. Anything over 2 ml titration (using 0.1% NaOH solution) can cause failure of the glycerine to separate -- under 1 ml is a good idea. Most waste oil is too high, and either needs to be refined with NaOH first, or cut with clean oil to neutralize FFAs.

7. You need to use more ethanol to get full conversion. Somewhere between 275 and 300 ml per liter of oil is about right for most oils. Coconut oil will need more, maybe 350 ml. Theoretical is about 180 ml per liter, and the rest is excess to drive the reaction all the way.

8. Even when you do all the above, getting the glycerine to separate is a matter of good luck and fervent prayer. Sometimes separation occurs just like a methanol batch. Other times you won't start seeing a glycerine layer for 3 or 4 hours, or maybe overnight. Then again, sometimes it NEVER separates. Until you get separation, you haven't made biodiesel. I've heard of folks who don't wait for separation -- they just pour the whole mess right into the tank, or do some kind of water wash and think it's good biodiesel. It might burn, but it's not biodiesel. It must separate.

9. If it doesn't separate, you can sometimes force it by adding some methoxide mix. You can also make it more likely to separate by including some methanol with the ethanol right from the start. For example, you could try using an initial mix of 5 to 7 parts ethanol and 1 part methanol. Give it a few hours to separate. If it doesn't, add some straight methoxide to the kettle, using enough methanol to bring the alcohols ratio down to 3:1 eth:meth, and containing another 2g of KOH per liter of oil. That usually initiates separation within an hour. Fresh, refined edible oil might even work the first time with straight ethanol. If you use a mixture of ethanol and methanol, you can get away with 275 ml of initial mix per liter of oil.

10. If you're not scared off yet, Good Luck!
-- Ken Provost

Anhydrous ethanol

To make ethyl esters the ethanol must be anhydrous, 99%+ pure -- with less than 1% water content. The purest ethanol that can be produced by ordinary distillation is only 95.6% pure, the rest being water, which interferes with the transesterification reaction in making ethyl esters. More common for home distillation is 170-190 proof -- 85-95% pure.

Members of Journey to Forever's Biofuels mailing list have succeeded in making ethyl esters using 85% ethanol they've distilled themselves, by removing the excess water with quicklime (CaO). See "The Manual for the Home and Farm Production of Alcohol Fuel" by S.W. Mathewson, Chapter 12 -- Drying the Alcohol, Drying with lime.

An easier method is to use 3A zeolite molecular sieve. Biofuels group member Ken Provost reports: "Zeolite (aka 'molecular sieve' ) works BEAUTIFULLY to suck the last bit of water out of distilled ethanol. I got a sample of Type 3A Molecular Sieve from Adcoa in Southern California:
http://www.thomasregister.com/olc/adcoa/molecula.htm

"I got a can of the 4-8 mesh -- little balls of rock about 1/8" diameter. They absorb about 20% of their weight of water over the course of a few hours. Take a liter of 95% ethanol, throw in 250g of the stuff, swirl occasionally, filter out the next day through a strainer, and presto! Anhydrous ethanol. Not expensive either -- US$2.05 a pound in 10 lb quantities, and reusable indefinitely. You drive off the water under a broiler for an hour."

An alternative is to run the ethanol vapours through 3A molecular sieve in a column during the distillation process.

Cornmeal Adsorber for Dehydrating Ethanol Vapors -- by Michael R. Ladisch et al., Laboratory of Renewable Resources Engineering, Purdue University. About half the ethanol now produced in the US is dried using corn grits. When the corn's drying capacity is worn out, it can be fermented and distilled to make more ethanol. This 1981 paper is the original work on the subject.

Cosmonauts Tsibliyev, Lazutkin: "... traces of alcohol".

"According to an intercepted communication, the Mission Control has demanded that the cosmonauts aboard the Mir Space Station get rid of the liquor-brewing still illegally installed aboard by one of the previous crews. It is the presence of the still, maintains a program official who would not be identified, that forced the recent shutdown of the main computer." Believe it or not.

The x86 still
http://www.exaflop.org/docs/x86still/
"To put it simply, the key components [of a still] are a heating device and a cooling device. Now the average PC has both a heating device (the processor) and a cooling device (the fan). The question we asked was 'By separating the processor from its fan and adding a few small components, could we convince an ordinary PC to distill alcohol?'"
Yes it could!
"I had needed to reboot the machine twice in that time (due to over heating) and decided to call it a day after Linux failed to restart (at the third reboot attempt)."
Maybe that's how they do it on Mir...

Flexible Fuel Vehicles and E85

In the US, E85 fuel is comprised of 85% ethanol by volume and just 15% petroleum. Though it hasn't received nearly as much publicity as it should have, many autos sold in the US are "Flexible Fuel Vehicles" (FFVs) that can run on E85 or gasoline when E85 is unavailable. More than 750,000 FFVs made their way to US showrooms in 2000. Ford, Daimler Chrysler, General Motors, Isuzu, Mazda, Mercury all make FFVs. The following websites have details of which models are FFVs.

If you have been taught the art by your old pappy livin' in those there hills, this book is for you. If you are a master crafter and know everything, this book is for you."

Building a Home Distillation Apparatus -- A Step by Step Guide, by Bob Lennon. Detailed online guide, focus on building and operating the StillMaker still: "does not enter into the domains of fermentation, recipes for making mash, beer, wine or any other spirits". Many homebrewers have built this still. Lennon says it "easily produces 95% ethanol in a single pass". Designed with the aid of computer programs which modeled continuously operating fractionating columns and the results were then adjusted to accommodate a batch processing operation. Now with two versions -- as well as the internal reflux model, Bob's added a new design for a reflux column with a top mounted condensor, using a beer keg as the boiler (the valved reflux model). Online and in Acrobat format, free.
