Ethanol: Good or Bad? In the pursuit of a cleaner renewable resource to fossil fuels, many scientist have found alternatives. Examples include solar, wind, biogas, geothermal, biomass energy and cellulosic ethanol. In the last twenty years, efforts have been made to reduce our dependency on foreign oil and ethanol has been an option. Ethanol is nothing new; in fact, it was first used in a motor built by Samuel Morey in 1826 (Ethanol History). Since the 1980s, the government started having oil companies...

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 Production

Ethanol Production Ethanol is the type of alcohol found in alcoholic drinks such as wine and beer. Its chemical formula is: C2H5OH. Glucose from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in yeast (single-celled fungi) are the natural catalysts that can make this process happen. Here is the word equation: Sugar → Ethanol + Carbon Dioxide ...

Analysis of Ethanol in Moonshine

Analysis of Ethanol in Moonshine | Using the GC-MS | Jennifer Greene | ------------------------------------------------- 4 May 2012 ------------------------------------------------- 4 May 2012 Introduction: In this experiment gas chromatography is applied to separate the water-ethanol mixture. This method is often used in the determination of alcohol in blood or urine. One obvious application is when law enforcement agencies need to determine whether or not someone is inebriated...

Cassava as ethanol

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...

Ethanol and Overall Material Balance

Balance (Non-reacting Systems) THR/WRU 1. A 40-mol-% aqueous ethanol solution is to be distilled into two streams: a distillate with 98% ethanol and a side stream with 60%. 98% of the alcohol in the feed is to be recovered in these two products; only 2% goes into the bottoms. If the bottoms product contains 2% ethanol, calculate the amount of the different streams per 1000 kmol of feed stream. Given: Recovery = 98% of ethanol in feed to distillate and side stream Feed, F xF = 0.40 Side...

Brine Shrimp and Ethanol Alcohol

The Effect of Ethanol on the Viability of Artemia salina as Environmental Indicators Biology 151 Laboratory ABSTRACT Artemia salina are used as environmental indicator species. They are used to test changes in their environment. A. salina is sensitive to toxins, temperature, and drugs. For the experiment, cysts were put into different amounts of ethanol alcohol and their viability was measured. The hypothesis used was if there is more ethanol alcohol, then the viability...

Ethanol sensitivity in Drosophila melanogaster based on genotype

 Ethanol sensitivity in Drosophila melanogaster based on genotype Alexa Shumate Department of Biology Randolph-Macon College Ashland, Virginia Introduction With a better understanding of the genes and behaviors associated with ethanol sensitivity, there will be new treatments available for alcohol dependence. The main problem in determining what causes dependence to alcohol is whether it is an environmental factor or if it is the genes associated...
