Ethanol is a clear colorless liquid that at low levels has a sweet taste, but at levels needed for fuel use it has a burning taste. Since 1990, when the government decided that gasoline burned had unsafe levels of carbon monoxide, ethanol has been added to gasoline in order to make it a higher octane level, burn cleaner, and to over all improve the emissions of gasoline. In order for an ethanol mixture to be considered …show more content…
an alternative fuel, it must be a blend of over 85% Ethanol and less than 15% gasoline. E85 is considered the lowest levels of ethanol to become an alternative fuel. E85 can be ran by Flexible fuel vehicles that come directly from the factory.
Ethanol can also be made from any biological feed stocks that contain appreciable amounts of sugar or materials that can be converted into sugar such as starch or cellulose.
Sugar beets and sugar cane are examples of feed stocks that contain sugar. Corn contains starch that can relatively easily be converted into sugar. Even most trees and grasses have cellulose that can easily be turned into sugar and then used in the making of ethanol. The ethanol process starts by grinding up the feedstock so it is more easily and quickly processed. Once ground up, the sugar is either dissolved out of the material or the starch or cellulose is converted into sugar. Then the sugar is fed to microbes and used for food, producing ethanol and carbon dioxide in the process. Lastly the ethanol is purified to the desired
concentration.
The benefits of ethanol are pretty clear, E85 is easy to handle and use. It is even possible to convert some of your equipment to use E85 for a low cost and does not have to replace whatever it is you are using. The use of E85 reduces the amount of petroleum fuels used, and it is "grown" in the United States so it does not need to be imported from other countries. E85 is also good for the environment because of the ease and how much less harmful it is to the environment over normal fuels. FFV's are very affordable and are readily available to anyone who is interested in buying them. The FFV's also can use normal fuel, however this is not a plus but makes the choice for drivers more convincing to buy an FFV just incase there is no E85 around when you need to fill up.
Many vehicles on the road today can run on blends of ethanol and gasolinemost on lower-level blends such as E10, and many on higher level blends such as E85. Because of the abundance of ethanol-compatible vehicles, the future is bright for ethanol as a fuel.
