1: What is Ethanol? | The hope for the future is to use other resources such as forestry & agricultural waste, switch grass, and other crops. When added to unleaded gasoline, ethanol makes the gasoline burn cleaner and cooler because it is oxygenated. | Ethanol is a fuel made by the fermentation of plant sugars. It is usually made from corn, sugarhum, and other grain products.
2: HOW IS ETHANOL | 1.) Milling -corn passes through the hammer mills that turn it into a fine powder substance 2.) Liquefaction -the powder is mixed with water and enzymes and goes to cookers where the starch is liquefied 3.) Saccharification -the mix is cooled and more enzymes are added to it so the starches can now be broken down
3: MADE? | 4.) Fermentation - Yeast is added to the new mixture to help the fermentation process which the mix flows through a series of chambers until fully fermented 5.) Distillation - the fermented mix, now called "beer", contains alcohol and solids. The mix moves through chambers that separate the two. 6.) Dehydration & Denaturing - the alcohol passes through a dehydration system that removes extra water and then a small amount of gasoline is added to the ethanol to prevent human consumption
4: What is the history of ethanol production? | In the late 1800's, ethanol was used for lamp fuel. Eventually, a tax was place on ethanol which nearly destroyed its sales. In 1906, the tax was lifted, and sales went back up. Then, oil companies started becoming more popular. The Model T was originally designed to run on ethanol but when oil prices decreased, so did the use of ethanol. The use of ethanol has been becoming more popular in the US and around the world since 1960 because of the Great Oil Crisis and also alternative fuel options.
5: Are there any byproducts after ethanol is made? | Livestock and poultry feed, fuel, distilled grains and solubles and syrup are some byproducts. | How much does it cost to make ethanol? | An acre of corn is about 7,110 pounds of corn. Which is 328 gallons of ethanol.- Planting, growing, and harvesting the corn costs money, which is about $347 per acre. Then once ethanol is made it would be about $1.05 per gallon of ethanol.
6: Besides the US, who else is making and using Ethanol? How & why? | Brazil and the US use ethanol fuel a lot. For one, its cheaper and it is a lot better for the environment, and our cars.
7: The Clean Air Act is is an act that helps protect the nations quality of air and ozone layer (Coming up with ways to power cars with less pollution). The last major change in the law was in 1990 during the Clean Air Act Amendment(of 1990). This was enacted by Congress. The Legislation passed it with minor changes. | What is the Clean Air Act?
8: Is ethanol good for our vehicles? | Millions of cars are powered by ethanol fuel. Ethanol fuel burns more completely and pollutes less than normal fuel. Its definitely good for the environment and our cars.
9: What type of laws/legislation surrounds the use of ethanol? | The Clean Air Act
