Drying the alcohol and blending it with gasoline

By The Late Robert Warren

Mashing and fermentation is covered in other areas of Robert's web site, and how to run the still is covered in the 40 pages of instructions I send out with the Charles 803 still blueprints.

 So, the thing you need to know next for making E85 is that you will need to remove the last 5 or 10% of water by a process called a molecular sieve. I know this sounds technical, but it is pretty simple, and cheap, too. A sieve is a strainer. The finer the screen, the finer the final product will be, as when you are sifting flower to remove any clumps or large particles. You can buy Zeolyle, which is a granulated product that will absorb water but not the slightly larger ethanol molecules. You need to specify that you want to buy the 3 A size (3 angstrom), as this is what you need for making 200 proof ethanol. Buy Type 3A in 10lb bags (looks like a small pea gravel) it is only a couple of bucks and it works very well to dehydrate the ethanol. We mix about 5 lbs in a 5 gallon can and let it sit with the ethanol overnight and pour the dehydrated ethanol through a screen, into another can the next day. To get the water out of the zeolite we just broil it on the backyard grill - it is reusable indefinitely. Or, you can dry it in the sun by spreading it on a tarp in the summer months.

Finally, you measure that you do really have 200 proof with a hydrometer. If you still have some water in your alcohol, it will separate out and settle to the bottom when you mix it with gasoline. Also, you should strain your 200 proof through a fine screen just to make sure you don’t have any zeolite particles that will clog up your fuel filter.
