The Problem and Its Background
Background of the study Bio-ethanol fuel has been used through these times and produced in many places specifically in Brazil and United States which contributes to the 87.1% bio-ethanol production in the world. Besides from being eco-friendly, inexpensive and less toxic, it is more preferred as a fuel for the materials used are the ones easy to find. (http://en.wikipedia.org/wiki/Bio_ethanol) As different from other fuels, bio-ethanol fuel is a form of renewable energy because the energy is generated using resources which cannot be depleted. It is usually obtained from the conversion of carbon-based feedstock which is considered as a renewable energy for it gets the energy from the sun by means of the process of photosynthesis. The photosynthesis itself performs due to the energy of the sun. (http://en.wikipedia.org/wiki/Bio_ethanol) In the production of bio ethanol fuel, the process of anaerobic respiration is included in the process of fermentation. In this process, the glucose (C6H12O6) from the feedstock is broken down into two molecules of pyruvic acid through glycolysis. With the presence of yeast molecules from the yeast (Saccharomyces serevisicie), the pyruvic acid is broken down into Carbon Dioxide (CO2) and Acetaldehyde. The acetaldehyde then acts as acceptor of the hydrogen which enables to produce a molecule of ethyl alcohol (C2H6O). This alcohol serves as a bio ethanol fuel for it comes from a carbon-based feedstock.
Statement of the Problem In our society, commuters and fuel-consumers use not only one kind of fuel. Some use ordinary fuel, leaded or unleaded but bio ethanol fuel is the known cheapest and eco-friendly fuel of all. (http://www.guardian.co.uk/environment/2007/mar/31/motoring.money) The use of bio ethanol is not new nowadays. In fact, there
