Ethanol Essay

Diesel is the fuel of choice in the European automotive market, due to the fact that it provides high-torque, efficient alternative to gasoline. The American view of diesel, however, is much less positive overall – most Americans remember the noisy, smoky diesels of decades past and know little about the quiet, clean diesels of the present. One of the best arguments for the switch to diesel fuel in the United States is that a fueling infrastructure is already in place, as transportation companies rely on diesel fuel to distribute goods across the United States (Is Diesel). This would negate the need to construct an entirely new infrastructure, which could cost hundreds of billions of dollars. Diesel is also considerably more environmentally friendly than gasoline, due to the fact that it is less refined (a process which uses large amounts of energy) and that it is more efficient than gasoline (ACEA). The combustion process in a diesel engine, which exerts high pressure on the fuel to ignite it, is the source of the motor’s increased

Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)

In the United States, ethanol is primarily used as a blending element in the production of gas and as an alternative fuel. More than 95% of the gasoline sold in the United States contains ethanol. Most of ethanol blending into U.S. motor gasoline occurs to meet the requirements of the 1990 Clean Air Act (RFG Fuel) and the Renewable Fuel Standard set forth in the Energy Independence and Security Act of 2007.

Ethanol is ethyl alcohol, a chemical that can be used as a vehicle fuel additive or replacement. It is sometimes called bioethanol because it is produced by fermenting and distilling plants. The United States is the world’s largest producer of ethanol and produces it primarily from corn. Ethanol made from other sources, known as feedstocks, are chemically identical. More than 95 percent of gasoline sold in the United States contains ethanol. Most of that is E10, a blend of 10 percent ethanol and 90 percent gasoline by volume. Mixtures with a higher percentage of ethanol, such as E15, are becoming more widely available, but the Environmental Protection Agency and automakers have not approved all vehicles to use these higher blends, so consumer demand is low.

Ethanol is an alcohol product produced from corn, sorghum, potatoes, wheat, sugar cane, even biomass such as cornstalks and vegetable waste. When combined with gasoline, it increases octane levels while also promoting more complete fuel burning that reduces harmful tailpipe emissions such as carbon monoxide and hydrocarbons. There are two processes for making ethanol: wet milling and dry milling. Many other fuel sources are made through a chemical process called. Many forms of biofuel have definite environmental advantages over petroleum-based gasoline and diesel fuel. However Ethanol contains 35% oxygen. By having more oxygen in fuel, it reduces the harmful tailpipe emissions. Ethanol also displaces the use of toxic gasoline components such

To start with, the lecturer debunks the author's first conjecture since ethanol removes carbon dioxide from the atomsphere. To elaborate in detail, the lecturer claims that although ethanol releases carbon dioxide as known as greenhouse gas, ethanol is made from plants such as corns. so the process of growing corns actually counteracts the release of the gas. This view is in direct opposition to the author's claim that ethanol is harmful as gasoline.

In the first video “Ethanol in Brazil”, the discussion is about the use of ethanol and how it influences many new endeavors in Brazil. Brazil uses ethanol to make alcohol and then uses the alcohol for fueling their cars. Brazil grows sugar canes, processes it into sugar juice, adds yeast, and this mixture produces ethanol. Using Ethanol in Brazil has since changed their dependency on foreign oil; Brazil went from 80 percent dependency on foreign oil to around 10- 15 percent dependency. In addition to the lower dependency rate, Brazil started a new endeavor called “Flex Fuel” cars. This car can run on ethanol, gasoline, or a mixture of both. One bystander in the video preferred to use the ethanol alcohol over gasoline because it was half the price of gasoline. One cool thing about the “Flex Fuel “car is that it has separate tanks for gas and alcohol, since alcohol does not work well with cold weather, drivers can decide to use gas

The author expresses some reasons which indicate that Ethanol is not an appropriate replacement for gasoline. The lecturer, however, refutes the claim since he believes that the arguments are not persuading.

Alcohols are being considered as modern day fuels because they are cheap to manufacture and some can be made in labs. There are four main alcohols that are especially being taken into consideration as alternative fuel sources. These four include: Ethanol, Methanol, Propanol and Butanol. The reason that these four have been considered is because A) They can me chemically/Biologically synthesized in a Lab, B) There are properties within these fuels that can be used within modern day engines, and C) These four fuels also have a high octane rating. The octane rating of a fuel refers to how much compression a fuel can go through before it ignites by its self. The reason this makes such a big difference within engines, is because when fuels self-ignite because they have been compressed too much, it can cause “knocking” which can damage the engine and also because it means that the fuel is more efficient and therefore you can get more kilometres per litre/KJ per Mol.

The sugar beets and sugar cane are very good examples of these feed stocks that contain the sugar. Corn contains starch that can easily be converted into the sugar that is needed. Even most of the trees and grasses have cellulose that can be easily turned into sugar and then used in the making of ethanol (Mukherjee 1 para 2).The ethanol process always starts by grinding up the feedstock which makes it more quickly and easily processed.

i. Ethanol is considered as a alternative fuel at a lower cost level in relation to gasoline. It is produced by fermenting sugars from a range of feedstock such as wheat and corn. Ethanol is blended with gasoline from E10 (5% ethanol - 95% gasoline) to E85 (85% ethanol - 15% gasoline).

As the number toxin spewing cars rises, pollution has presented itself as a major problem in urban areas. There have been many solutions presented to help solve this problem, but few have been widely accepted by the general public. I believe the pollution problem is one that cannot be solved in one big step, but in smaller steps. I see Ethanol use as one of those steps. The intention of this proposal is to recommend an approach that would lead to widespread use of ethanol.

The exhaust fumes that ethanol give out are a lot cleaner than other fumes (has better complete combustion).

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.

What environmental benefits do we receive form an influx in ethanol as an alternative fuel? First let’s look
