Jun 04, †Ј The most common use of ethanol as a fuel is in mixtures of motor gasoline. Most of the gasoline sold in the United States contains some fuel ethanol. The exact amount may vary by region. In general, the ethanol content of motor gasoline does not exceed 10% by volume. Ethanol as Fuel, is it true? Yes, the same Ethanol, which is an important ingredient of all alcoholic drinks can be used as a good alternative fuel. Ethanol, also known as Ethyl alcohol, grain alcohol, bioethanol or simply alcohol is made from barley, corn, sugarcane or similar crops by a fermentation process.

Now you may ask How alcohol is ethanoll eco-friendly fuel? Are there any advantages or disadvantages? Let us discuss each aspect in detail so that you can easily understand and make your valuable contribution to save our environment.
Ethanol is an organic compound with two carbon, 5 hydrogen atoms and a hydroxyl -OH group. Ethyl alcohol is volatile, colorless and burns with a smokeless blue flame. Apart from medicinal and recreational alcoholic how to block punches in boxing usage, ethyl alcohol is widely ass as an alternative fuel when blended with gasoline.
The basic raw materials for manufacturing ethyl alcohol are Starch Ч corn, wheat, barley, and potatoes. Sugar crops Ч sugar cane, beetroot, and sweet sorghum.
Cellulosic feedstocks Ч Crop residue or wood chips. In the U. The most important factor is ethxnol Octane rating. Do you know what an octane rating is?
So you got an idea of octane rating now what it has to do with ethanol? Ok, I will explain that, but before this, let me tell you something.
Octane Rating of Ethanol : Thus, we found that Ethanol has a higher octane rating than gasoline hence it provides premium blending properties. Increasing the octane rating for xs is expensive and ethanol blending would be a cheaper option.
Apart from economical benefits, it ad harmless for the environment too as ethanol burns more cleanly and completely than gasoline erhanol diesel fuel. Different parts what is one business day equal to the world use different types of raw materials for making ethanol as pointed out earlier. The bioethanol production process remains almost the same whether you use corn or sugarcane.
Ethanol fuel is made by the following process Corn kernels are finely ground into the powdery form which is mainly starch. Water is then added to make a slurry. The slurry is heated along with enzyme alpha-amylase which acts as a catalyst to break long starch molecules into smaller pieces.
The slurry is cooled and a second enzyme glucoamylase is added to it. This ethanpl converts liquid starch into sugars glucose. Yeast is added and the slurry is allowed to ferment. The product of fermentation is distilled and the evaporated vapor is collected overhead.
The liquid ethanol is then dehydrated to remove excess water. After the dehydration process, pure ethanol is formed which is suitable for blending with gasoline. Sugar containing raw materials such as sugarcane, sweet sorghum, and sugar beet are widely used to produce ethyl alcohol. In Indiaethanol is produced from sugarcane molasses due to the wide availability of this crop.
Sugarcane stalks are crushed and squeezed to extract sugar cane how do you become a zumba fitness instructor. The juice is then transferred to a fermentation tank containing yeast where ethanol is zs. The process is similar to the starch fermentation as described above.
This process is rather old and known as first-generation biofuels. Ethanol burns more cleaner than gasoline thus creating fewer toxic emissions. Ethyl alcohol introduces more oxygen into the fuel mixture and improves combustion efficiency. It does not contain toxic substances like benzene and lead, thus leading to low levels of toxins yo the environment. As ethyl alcohol how to use ethanol as fuel obtained from biomass it produces fewer greenhouse gases GHG as compared to conventional fuels thus reducing the effect of global warming.
Any country that produces starch or sugar crops can cut their dependency on conventional fuels as bioethanol is economical to manufacture. Over the years, significant technological improvements resulted in increased efficiency of corn and ethanol production making it cost-effective.
In addition to corn and sugarcane, a wide variety of crops and feedstocks can be used to uze bioethanol. Ethyl alcohol has a high octane rating, thus it acts has high-performance fuel with better antiknock properties.
Countries that are not oil producers such as India are heavily dependent on the supply of crude oil which is quite how to wire 1 4 jack. Bioethanol once produced locally could lead to lower fossil fuel imports. Adopting furl as a fuel can incur huge potential savings for any economy. Although ethyl alcohol may not replace conventional oil fully in the near term, it hpw reduce ethanoll total amount of oil import. It also helps to prevent winter starting problems by acting as an antifreeze.
Bioethanol production supports local farmers and creates domestic jobs in rural communities. Bioethanol industry has the potential to create new markets for allied industries such as biomass, agriculture, forestry, construction, food processing, etc.
This is like a chain reaction that helps to strengthen and diversify the rural economies of a country. Locally grown natural raw materials are the feedstock for bioethanol production.
Almost every country grow their foodgrains locally thus, the finished product is readily accessible to all. Raw materials such as corn or sugarcane if overgrown for a prolonged period then the minerals and other organic supplements are totally lost from the soil. Thus proper crop ro is mandatory to improve the soil howw. Overall, the energy produced by ethanol could be on the neutral side if we include the additional energy required for transportation and processing.
The countries that ass ethanol as fuel are zs it in smaller quantities just to meet their domestic fuel demand. In that way, bioethanol would not be a profitable source fiel income if it is exported to other countries.
Due to the low energy content in ethanol fuel about two-thirds that of gasolinethe milage of your vehicle would be less. Thus you can see how ethanol fuel results in lower fuel economy. Us order to meet the growing fuel demand, feedstock cultivation requires large scale production. A large piece of land might not be a problem in some countries but renting and leasing would incur an additional cost.
If bioethanol aw is more then farmers will concentrate more on ethanol production rather than other essential commodities such as sugar. Thus, over time, the cost of essential commodities may rise leading to high food inflation. Ethanol has an ability to absorb water and its corrosive nature makes it difficult to transport through the pipelines over long distances. Due to its water affinity ethyl alcohol is not suitable for marine environments too. Ethanol is gaining support nowadays as it is environmentally friendly and hhow reduced emissions.
During its implementation, it must be noted that not ax vehicles how to activate mighty eagle on angry birds run on bioethanol fuel especially the older ones.
There are ample benefits of ethanol fuel and on the other hand, there are certain limitations too. There is always ethhanol issue in the supply of feedstocks especially for countries like India where sugarcane cultivation is cyclic. The second-generation 2G biofuels technology for ethanol production is still in the nascent stage that needs to be upgraded and refined for commercial usage.
But it is true that even after all these limitations, ethanol-based fuel is still an important alternative as eethanol to fossil fuels. Do you have any comments on the article?

Mar 24, †Ј Ethanol (E10) PROPER USE Guidelines: Always add a Fuel Stabilizer as soon as you get fresh gas. Shake the fuel mixture in your gas can to stir up any small amounts of water that may have collected at the bottom. Store fuel in an air tight gas container (no vent caps). May 26, †Ј Fermentation is the most common method for producing fuel ethanol The most common ethanol production processes today use yeast to ferment the starch and sugars in corn, sugar cane, and sugar beets. Corn is the main feedstock for fuel ethanol in . Nov 05, †Ј Another reason ethanol is such an attractive fuel option is that itТs basically liquid energy. Ethanol is a clear liquid that packs a lot of energy into a usable, storable, and transportable.
What if there were a fuel that was affordable, renewable, and produced right in your own community? It was called alcohol, and it was a clean-burning fluid generally sold as lamp fuel. Only recently have we taken a renewed look at alcohol fuel Ч now more commonly known as ethanol Ч and its potential as a domestically sourced fuel for transportation.
What I am going to tell you is how to make your own fuel to use in your vehicle or in other gas engines, such as a motorcycle, tiller, or lawn tractor.
With a little specialized equipment and know-how, you can turn these materials into alcohol fuel, and it will cost less than you would pay at the pump for gasoline or commercially produced ethanol. If you grow your own corn, you can distill more than gallons of ethanol from 1 acre of corn.
If you drive less than 10, miles per year, you could produce all your own fuel from 2 acres of corn Ч and, granted, a lot of labor. One of the strongest arguments for ethanol fuel is that we can make it ourselves, with no dependence on foreign resources.
He envisioned farms across the country providing the crops needed to make both fuel and food. Ethanol is a clear liquid that packs a lot of energy into a usable, storable, and transportable form Ч only petroleum can compete with ethanol on an energy-per-volume basis. Would-be fuel producers must apply for a permit to make their own fuel, but after the energy crisis of the s, the federal government substantially streamlined the permit process.
Recognizing the difference between beverage and fuel spirits, the Department of the Treasury came up with a simplified application for an Alcohol Fuel Producer permit Form A proof gallon is one liquid gallon of spirits that is 50 percent alcohol at 60 degrees Fahrenheit.
Each state has its own permit requirements, generally modeled after the federal rules. Ethanol production is a natural process that comes about through the fermentation of carbohydrates Ч organic compounds containing carbon, hydrogen, and oxygen.
Plants and crops produce carbohydrates in the form of starches, sugars, and cellulose. The bonds in the molecular structure of celluloses are difficult to break, but most plant starches and sugars are easily broken down into simple sugars with the addition of heat, water, and enzymes. Once the simple sugars are established, yeast is added to feast upon the sugar, reproduce and, in the process, expel carbon dioxide and alcohol. The choice of raw material is an important factor.
Crops with a high sugar or starch content are ideal, but nearly any crop cull or surplus can work if used before spoilage sets in , so you can choose the most economical and sustainable materials available to you. Apples and other small fruits, potatoes, beans, wheat, rye, and sorghum grains are all potential candidates Ч as is cheese whey, the milk sugar left over from processing.
Food-processing wastes from the beverage, baking, snack, and confectionary industries are notoriously high in sugar or starch content and can provide an alternative to direct-from-field sourced feedstocks. After fermentation is complete, the ethanol must be distilled from the water. This is best accomplished with a reflux still, which is equipped with a distillation column. The column uses a series of perforated plates or packed compartments to remove the water in a process called fractionation.
As the heated water and alcohol vapors rise through each stage, a progressively stronger alcohol vapor is created. During distillation, column temperature must be controlled to take advantage of the different boiling points of the two fluids. The alcohol vapors rise, while the water condenses and drops back to be reintroduced as a vapor mix again and again. The most potent alcohol vapors exit at the top of the column to be cooled by a water condenser and collected as proof 96 percent pure ethanol.
Besides, the small amount of water present does not hinder engine performance. Car engines have to be modified to run on straight ethanol. Fuel-injected engines can have their injectors replaced for greater flow, or the fuel pressure increased.
Engines can be further optimized for ethanol by preheating the fuel and air, varying the heat range of the spark plugs and boosting the compression ratio. So what does it take to set up a small-scale distillery? That depends on how small an operation you want. A simple batch still can be made from an old water heater and a length of 3-inch conduit and heated by wood or natural gas. On a more practical scale, building a 6-inch column still will put you in the 6-gallons-per-hour production ballpark Ч a substantial yield, but one that comes with additional cost.
Centrifugal pumps, plumbing, and valves are also a necessary part of the plan, along with a hydrometer, several thermometers, and pH and sugar testing tools. A 6-inch column coupled to a to 1,gallon tank will run a batch in four to seven hours. Used distillation columns are sometimes available through farm and industrial auction dealers.
The cost to produce ethanol will depend on how much effort you put into the process. Even using culled feedstocks will not guarantee an economical product if you waste energy during production. The source, duration, and degree of heat input are significant factors that can be economized with the use of efficient enzymes and heat-recovery designs.
Using alcohol-tolerant yeasts with nutrients improves conversion efficiencies as well, and making the most of useful byproducts such as high-protein distillers grains adds to the bottom line. The fermentable percentage of common grains and root crops varies drastically between 16 and nearly 80 percent. Probably more important is the alcohol yield per acre, which can range from about gallons for field corn to gallons for sugar beets, to nearly gallons for sugar cane, sorghum, and Jerusalem artichokes.
Other crops may have lower yields, but offer advantages in conversion, storage, or processing. The table below is a breakdown of representative costs and recovery for a small operation, which will vary depending upon your particular situation.
And keep this in mind: Whether you can make ethanol on a small scale for less than the cost of gasoline today is not the only question. He currently lives in Hendersonville, N. It will destroy most rubber fuel lines.
