The Pros And Cons 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.

Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, EtOH, and grain alcohol. Ethanol is widely produced by processing grains such as corn or starch and sugar crops. The grain is first milled, then fermented with yeast and different enzymes to turn the grain 's starches into alcohol(EPA). A distillation process then increases the ethanol concentrations, basically the same process a whiskey maker would use to make whiskey. Of course, law mandates that a denaturant is added, making the liquid unsafe for drinking. In the process, waste grain is produced and sold as farm animal feed. Bioethanol, can be made from many types of trees and grasses, but the procedure is much harder. The chemical formula of ethanol is the same whether it is made from starch and sugar-based feedstocks, such as corn grain (widely used in United States), sugar cane (Brazil), or from cellulosic feedstocks (such as wood chips or crop residues).

This report extensively analyses the production and breakdown of Ethanols, to assess its properties and their relation to being a fuel. The use of Ethanol as reliable source of renewable energy and its current effects on society. The potential use of ethanol as an alternative to coal and fossil fuels, the advantages and disadvantages of Ethanol.

Fuels produce energy to allow things like machines to properly function. For example; about 10% of ethanol is used for motorcars (Blume, 2016). Alcohols are used in many ways, in everyday situations. For example octane is used in motorcars as fuel and ethanol is used as an alcoholic disinfectant.

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.

You wake up this morning, put on some shoes, and head to work. It's early—you're feeling a bit slow and your gas tank is almost empty. You stop at your local gas station, pick up a coffee and ten bucks in regular unleaded gas. Harmless, right? Wrong. That gas you just put in your tank contains up to ten percent ethanol (alcohol based fuel). That might not sound so terrible right now, but potentially it can be.

Adult, male and female C57BL mice were used and were bred from our own facilities at Indiana University of Pennsylvania.

The production of Ethanol has been happening for many of years. The production of Ethanol is a form alcoholic beverages, which humans have been drinking for many of hundreds of years. Ethanol is produced when alcoholic fermentation occurs. Alcoholic or Ethanol fermentation is a biological process that produces ethanol without needing oxygen. What is needed for this process to work is glucose and yeast. The production of alcohol or ethanol is the chemical reaction that happens when yeast breaks downs glucose (sugar). Glucose + Yeast → Alcohol + Carbon Dioxide. The different types of alcoholic beverages come from the different glucose used, like the glucose from different fruits. Whenever producing Ethanol or Alcohol you need to make sure that it is being brewed into a vessel which allows the carbon dioxide to escape and prevents oxygens from coming in.

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

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).

Since the invention of the internal combustion engine, car makers and consumers have been filling the gas tank with just that, gasoline. Starting out with leaded gasoline then slowly switching to unleaded gas in the late 1960s until catalytic converters, a new auto part which can only run on unleaded, were made mandatory in 1975. However over the past couple decades there have been a new contender in the fuel marketplace to power consumers’ cars. Ethanol is defined in World Book Student as “a type of alcohol found in alcoholic beverages and used as an automobile fuel” (Sheehan 1). Sometimes called ethyl alcohol or grain alcohol, has been an additive to gasoline since its introduction. The purpose was to reduce dependence on foreign oil,

Drinking alcoholic beverage is already a part of our routine. We may not drink every day but if there is an occasion like birthdays, anniversaries, job promotions, reunions or if you are heart-broken, alcoholic drinks are always present. Not all people are drinking beverage because they are happy, sometimes, others are drinking because they are sad of losing a family or they are feeling pain because of a recent break up.

We all have the right to make our own decisions of whether we want to drink alcohol or not, and how much we want to consume. In class, we discussed different topics that all come under alcohol. Firstly, we read articles that outlined the rates of death caused by alcohol. From these articles, most deaths dealt with university students around New Zealand because of cheap alcohol prices, peer pressure, continuous parties organized by students and many more. Thereafter, we were also able to generate questions that were thoroughly discussed with our teacher. Initially, we debated if alcohol should be banned or not because half of the class agreed whilst some disagreed. Nextly, we talked about the reasons of why people consume alcohol and finally, the good and bad sides of drinking alcohol, along with their solutions. However, after all these deliberations, I have decided to elaborate on the topic above; “ALCOHOL SHOULD NOT BE BANNED”.

Blending ethanol with diesel fuel has several issues in terms of performance and emission lev-els. A number of studies have examined the effect of ethanol on thermal efficiency, brake power, fuel consumption and emission levels. Some research [114, 120, 125, 126] obtained dif-ferent results in terms of performance and emission levels. Most of this research agreed that ethanol causes an increase in fuel consumption (BSFC) and a decrease in the efficiency of the diesel engines. Chen et al. [120] showed that ethanol could decrease some types of emissions such as smoke and PM because high oxygen content helps to complete the combustion. When vegetable methyl ester was added to

Ethanol is made from a renewable source and does not harm the environment in any way. E10, containing 10% ethanol has an octane rating of 94 or 95. Although E10 will make the vehicle run better, it will be consumed faster because it does not contain as much energy. The chemical composition of ethanol is C2H5OH. As shown in Diagram 2. But because E10 if only 10% ethanol the other 90% will be pentene (as shown in Diagram 1). This is because E10 is mixed with petrol.
