Corn Ethanol Controversy And The Chemical Formula Of Ethanol

Generally ethanol is an alcohol found in alcoholic drinks. At 100% concentration, it is pure and a colourless liquid with a strong odour (due to weak Van der Wall forces :D. Ethanol is produced by the fermentation of carbohydrates in yeast cells and is used frequently as a solvent.

Corn can be used to create a fuel from corn pellets called ethanol.This colorless liquid can be added to gasoline to reduce the amount of gasoline burned. This can reduce the amount of pollution used by cars. It states in paragraph 2 on page 1,”Shelled corn can be dried and formed into pellets.”.These pellets can be burned

Ethanol is now found in most gasolines, except for the few and far between pumps that sell ethanol-free fuel. Ethanol acts as a “filler” in gasoline, because it is much cheaper than many gasoline components, however it comes at a price because ethanol infused gasoline procures about 33% less energy than ethanol free gasoline, dropping its competitiveness towards diesel even more. (Energy, 2015) Ethanol gasoline types include E10, E15, and E85. E10 represents gasoline with a 10% ethanol content, which is the norm now for most gasoline types, and what will mostly likely be in normal unleaded gasoline. E15, 15% ethanol, can only be used in flex-fuel or light duty cars because it produces not nearly enough power to run a large gasoline engine without major modifications. (Energy, 2015) E85, meaning that it is composed of 85% ethanol gasoline mixture (51-83% ethanol), and can only be used by special flex-fuel

The ethanol production process starts with growing corn, on average an acre of corn yields close to 7,110 pounds of corn that require 140 gallons of fossil fuels to grow through the use of liquid fertilizer and powering machinery (Ethanol Fuel from Corn par. 4). The corn is harvested and transported to an ethanol refinery where it is ground, then water is added to create a mash in which enzymes break down the corn into sugar, afterward the sugar is mixed with yeast and fermented to produce ethanol (Ethanol Fuel: is ethanol par. 9-10). During the process of growing and processing the corn needed to manufacture one gallon of ethanol, it requires 131,000 British Thermal Units (BTU) to generate a gallon of ethanol while a gallon of ethanol produces only 77,000 BTU (Ethanol Fuel from Corn par. 5). The net ratio of energy for ethanol production is undesirable because ethanol has barely over half of the total energy needed to produce ethanol. Other materials can produce ethanol, such as switch grass or wood biomass, however, their energy returns are just as atrocious, needing forty-five percent and fifty-seven percent more energy to produce ethanol than it provides, respectively (Lang par. 5). This net

Corn ethanol can't avoid being ethanol made from corn that is used as a biomass. Corn ethanol is conveyed by strategies for ethanol maturing and refining. Corn ethanol is for the most part utilized as an oxygenate in fuel to make a low-level blend. To a lesser degree, it is utilized as fuel for E85 flex fuel vehicles. Corn is the fundamental feedstock utilized for making ethanol fuel in the united states.

Growing corn for ethanol could be beneficial for the economy by providing more jobs as needed on the farms. The farmers would have to purchase more farm equipment which would boost our economy even more. Plus the fact that the US could cut out the middle man or the need to import ethanol from other countries; thus, keeping money inside our country and not giving it all away to other countries. This all looks good on paper for the economy but when it comes to the environmental side of things scientist seem to think there is more of a downside to this. I can see where the ethanol use as fuel from corn would be of great importance to the environment as it would cut out the need for the bad emissions released by straight gasoline.

Ethanol is a clear, colorless liquid that is made by fermenting sugars produced from corn starch. A lot of corn refining factories make ethanol and other corn products like starches and sweeteners so that manufacturing costs can be kept low. During the making of ethanol, corn refiners also produce valuable co-products such as corn oil and corn. Ethanol may also be produced using other starch crops.

So we've listed off all the reasons why ethanol is better than E85. Now what? The goal of my solution isn't to convert the whole world over to E85 and flex fuel cars. That's not realistic. The goal here is to utilize the current amount of flex fuel cars on the road to reduce emissions. According to the EPA, there are currently 6 million flex fuel vehicles on the road, and all of them aren't utilizing their capacity to run renewables fuels(“Business Case for Installing E85 at Retail Stations”). I'm aiming to bring that number as close to 100% as possible. Ethanol can only help reduce global emissions, and for those 6 million vehicles this is a very simple change to make. They literally just have to change which nozzle the stick in their car

The article states that ethanol is not a desirable replacement for gasoline and provides three reasons of support. The professor explains that ethanol is a good alternative to gasoline and refutes each of the author's reasons.

Ethanol is used to create perfumes but more importantly is mixed with gasoline to make it more efficient. The potential for using more ethanol is that it is safer for the environment and is also better on your car than gasoline. It is safer because it reduces air emissions when mixed with gas. The reason it is better on your car is because it keeps the injectors and fuel line cleaner than gasoline does.

“By 2011 most cars on U.S. roads could run on blends of up to 10% ethanol (E10), and manufacturers had begun producing vehicles designed for much higher percentages. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol (E85). By early 2013 there were around 11 million E85-capable vehicles on U.S roads. In January 2011 the U.S. Environmental Protection Agency (EPA) granted a waiver to allow up to 15% of ethanol blended with gasoline (E15) to be sold only for cars and light pickup trucks with a model year of 2001 or later. The EPA waiver authorizes, but does not require stations to offer

Well we all know that the energy system is very unstable because the total energy available on the earth is limited, and man has exploited all the conventional technologies to fulfill his needs. By the use of these conventional technologies, the world also has a disability, with problems such as global warming. Consumption of energy by man increased gradually as his wants also increase. The conventional energy resources mainly include fossil fuels, but research shows that this fuel source will be depleted completely in approximately 20-25 years. This could cause major setbacks around the world. As a result, we need an alternative source of fuel that could keep the world running on its wheel. One possibility is ethanol. Chemically extract

Ethanol or as we know as alcohol in our beverages can be made from any fruit or vegetable that performs photosynthesis which produces glucose shown As required as the reactant of the previous equations.

Ethanol is an alcohol, and its chemical formula is C2H6O. This chemical formula can also be written as CH3CH2OH or C2H5OH. It is made of nine atoms that include: two carbon (C) atoms, six hydrogen (H) atoms and one oxygen (O) atom. Its chemical structure is illustrated in the following picture. Here, there is __methyl group__, which is the CH3-, a __methylene group__, which is the –CH2- and a __hydroxyl group__, which is the –OH, in the chemical structure. Ethanol can be abbreviated as __EtOH__.

This essay will first discuss the advantages of using corn ethanol as the main source of fuel in the future, such as the renewable features of corn itself, and the benefits of using corn ethanol as an additive of gasoline instead of using gasoline alone. However, everything has its strengths and weaknesses. Therefore, the second part of the essay will discuss some of the weaknesses in applying the fuel into practical usage. For example, corn ethanol currently encounters technical limitations serving itself as a standalone fuel, meaning that corn ethanol can only function by combining itself with a certain amount of gasoline, while gasoline is a kind of fossil fuel. Lastly, this essay will conduct a comparison with other renewable resources in the world, including solar power, other biofuels, and hydrogen fuel.
