Alcohol based fuels are used as alternatives to fuels that come entirely from non-renewable resources. The most common of these are ethanol and methanol. These two substances have a few similarities‚ but also significant differences. The similarities are so few that they can be listed concisely; just appearance and smell are similar for these two chemicals. If an individual were presented with samples of each of these chemicals‚ they would have to ignite it or consume it in order to tell the

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. 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

been experimenting with different types of fuels and adding to gasoline to make it more efficient. This is when ethanol made its debut into the fuel industry‚ as an additive to gasoline. Ethanol is put into gas as a combatant against water‚ which can find its way into fuel tanks of vehicles. It reduces the effect that this water has on the health of the vehicle‚ and as a result increases gas mileage‚ and also increases the amount of complete combustion. Ethanol consumption has severe drawbacks pertaining

Brine shrimp and Ethanol research paper Ethanol is an alcohol substance that has effects on growth in organisms. Brine shrimp are used to tell the different levels of acidity in environments. Organisms absorb the substance around it; sometimes it has no effect on them sometimes it does. The best way to figure out if the environment has an acidity level too high for normal growth is to put the organism in a dish and watch carefully and observe any changes that occur in comparison to a normal organism

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

of alternate fuels The truth about the manufacturing and use of alternate fuels‚ as with everything else in life‚ is a mix of benefits and cost. Electricity is one of the alternate fuels that made it to production. The Chevy Volt is one such vehicle. The problem with this car is that it cost $41‚000 to buy one‚ and the battery life for a charge is only 37 miles. There would be no value for us to use electric cars. (Courture‚2011).

demand for fossil fuels growing through out the world‚ there is with out a doubt a lack of supply for this demand. The United States is the world’s highest consumer of fossil fuels because of the amount of Automobiles that we have on the roads every day. This is not one of the statistics that a country should be proud of being at the top of. Since the United States is the leader of the consumption of these fossil fuels‚ the government is making an effort to look for alternative fuels that we can use
