Paraffin wax produces more energy per gram than Ethanol based on our test results‚ and simply by the molecule comparison itself. Since Ethanol is an oxygenated molecule and already contains oxygen‚ it cannot burn at the same intensity as Paraffin does‚ since Paraffin is

Luke Fancy Pro/Con Paper: Pros of Ethanol Due: 12/07/11 Ethanol was first used in 1908 on Henry Ford’s Model T. The Model T was designed so that it could be run on either gasoline or pure alcohol. When asked why he wanted to run the Model T on alcohol‚ Henry Ford replied by saying‚ “It is the fuel of the future.” The use of ethanol continued through the 1920’s and 1930’s in an effort to keep a United States ethanol program alive. Although the effort was unsuccessful‚ oil supply problems

Ethanol Ethanol is easily soluble in water in all proportions with a slight overall decrease in volume when the two are mixed. Absolute ethanol and 95% ethanol are themselves good solvents‚ somewhat less polar than water and used in perfumes‚ paints and tinctures. Other proportions of ethanol with water or other solvents can also be used as a solvent. Alcoholic drinks have a large variety of tastes because various flavor compounds are dissolved during brewing. When ethanol is produced as a mixing

USA over a Barrel The cost of a barrel of oil this summer reached a record high of nearly $100. How has this happened and how much higher could oil go? The United States dependence on foreign oil is at an all time high. Nations supplying this oil are pumping at a record pace and maximum capacity. If any of these nations fail to supply the U.S. because of a terror attack or bad relations‚ the economy would be negatively impacted. How can the U.S. reduce dependence on imported fuels and diversify

Ethanol What is Ethanol? Ethanol‚ which is sometimes called ethyl alcohol‚ pure alcohol‚ or grain alcohol is defined as‚ “a high octane‚ clean burning‚ American- made renewable fuels.” Ethanol is an increasing important aspect of our society and its popularity is becoming more widespread on a daily basis. Ethanol‚ a substance made out of Sugar-cane‚ maize‚ sorghum‚ wheat ‚ and other grains‚ has become one of the main viable source of energy in the world. In countries like South

In the field of Science‚ this study contributes a lot for the reason that we can find alternative for paraffin wax as main component in candle making‚ besides paraffin was derived from petroleum and the later is much expensive. This study contributes knowledge to the researchers and also to the community in the sense

three times as much carbohydrate for fuel ethanol production (Comis‚ 2008). Ethanol production from fresh cassava roots using a low-temperature process was evaluated on a pilot-plant scale. The application of low-temperature cooking to cassava starch followed by a dual enzyme action resulted in an ethanol yield comparable to that of a traditional high-temperature cooking process. Pressurized distillation gave a satisfactory recovery efficiency of ethanol but was slightly lower than that obtained

After reading Ethanol Madness in The Economics of Public Issues (Miller‚ Benjamin‚ & North)‚ most of America is not benefiting from the production of ethanol. The only ones benefiting from ethanol requirements are ethanol producers‚ farmers‚ Brazilian farmers and politicians. Congress and the United Sates government are both benefiting from the ethanol requirements and the import tariff on ethanol. In the chapter I learned that ethanol is not as renewable as it seems. It is an alternative to biofuel

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
