will explore the use of ethanol as an alternative fuel source. Ethanol is considered a renewable energy resource; as it is derived from crops such as: corn‚ sugarcane‚ beets‚ as well as‚ other organic materials. The use of ethanol could decrease our dependence on ever depleting supplies of fossil fuels; such as oil. In this paper‚ I will briefly review how ethanol is produced in different parts of the world. I will also review several of the advantages of using ethanol as a renewable source of

Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

Ethanol fuel is ethanol (ethyl alcohol). Ethanol‚ also called ethyl alcohol‚ pure alcohol‚ grain alcohol‚ or drinking alcohol‚ is a volatile‚ flammable‚ colorless liquid. A psychoactive drug and one of the oldestrecreational drugs known‚ ethyl alcohol produces a state known as alcohol intoxication when consumed. Best known as the type of alcohol found in alcoholic beverages‚ it is also used in thermometers‚ as a solvent‚ and as a fuel. In common usage‚ it is often referred to simply as alcohol or spirits

to evaluate ethanol as a fuel‚ the experiments are Fermentation and Calorimetry. Fermentation will find the best combination of sugar and yeast for optimum ethanol production and the Calorimetry experiments test ethanol against other alcohols and fuels to see how it matches up in terms of energy production. Fermentation shows glucose and baker’s yeast as the fastest producers of ethanol and the calorimetry proves that ethanol and other alcohols produce more heat energy than other fuels. Introduction

Using ethanol as an alternate fuel‚ or fuel extender includes a heterogenous agglomeration of advantages and disadvantages. On cars: ethanol is preferable to lead as an octane booster. A 10% addition of ethanol to petrol is more effective than lead at boosting octane rating (+2.5) and making car run smoother. It’s cheaper than lead‚ and ethanol-blended fuels leave no gummy deposits‚ thus keeps engine clean. Although a minimal 10% ethanol blend should be compatible with internal combustion engines

The main factors of this article called “Methanol--the fuel in Waiting” explains how Methanol could both have positive and negative effects in the environment and the economy. The article discusses how methanol could be another alternative to gasoline and it is a made from natural gas‚ which makes it easier to make and use. Methanol (see Figure 1) is that it is the simplest alcohol with a chain of one carbon atom with three hydrogen atoms attached. The characteristics of this simple alcohol are

Fuel is one of the important resources in our society. We use the fuels to support our living‚ produce electricity‚ heat homes‚ and operate machinery. Since the fuel is a limited resource‚ the fuel scarcity will be a big issue in the future. The price of the gasoline is currently on the rise. NASCAR cut the volume of fuel cell from twenty gallons to thirteen gallons each car. There is a high demand for a new energy. After the issue of fuel crisis was brought up‚ the society started to be interested

the listening have a conflict of opinions about ethanol fuel. The writer believes that ethanol fuel is not a suitable alternative for gasoline‚ while the lecturer claims that passage state is not convincing and disputes those ideas presented in the passage with several proofs. First of all‚ the author asserts that the ethanol fuel would not assist to fix global warming problem. Conversely‚ the lecturer brings up the idea that augmented of ethanol fuel does not adversely affect the environment. In other

ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

fossil fuels due to the lacking of oil‚ gas‚ etc. An alternative energy source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil
