Ethanol Basics
The use of ethanol as an alternative fuel is becoming increasingly popular by ever conscious consumers wishing to do their little bit for the planet. It may even be a better alternative to bio fuel, it seems that it is a lot more pleasant to make at any rate.
What is Ethanol? Ethanol is a grain alcohol, or plant mass formula derived from the natural sugars found in bio mass, or vegetation such as corn, wheat, barley, potatoes and sugar cane. This is then processed to make a renewable form of fuel or fuel additive, which is both cost effective and good for the planet. Many cars are able to run on Ethanol and gasoline mixtures. Although at the moment, the mixtures are only a ratio of 10% Ethanol, to 90% fossil fuel.
Benefits of Ethanol
There are many benefits of using an alternative fuel such as Ethanol, for starters it is a renewable resource, fossil fuels used to make gasoline is not renewable, so one day they will run out, it is because of this that people, have become more aware of alternative fuels and additives. Another good reason for using an alternative fuel such as Ethanol is the reduction of pollution, we only have one planet and if we keep polluting it we may very well find ourselves with nowhere to live. Any steps that we can make toward reducing pollution is a positive. Another good reason to consider a fuel alternative such as Ethanol is that it is far more cheaper to use and make, the main cost involved in making Ethanol is in the processing method.
How is Ethanol Produced?
The process used consists of 8 stages, corn is the main product used in this method,
Milling the corn, to make it into a fine powder, or meal Liquification, which is mixing the meal with water and Alpha-amylase, then heating it at temperatures of 120-150 deg Celcius, the heat reduces bacteria. Saccharification, is the process of cooling the mash, and adding glucoamylase, this converts the starch to dextrose, Fermentation, is where the yeast is added to ferment the sugars to convert it to Ethanol. This process consists of the mash going through several different tanks, and takes about 48 hours.
Please note that this procedure is risky and I do not recommend making biodiesel without further research of the process, these are just general guidelines of the making process, if you wish to actually make your own bio diesel please consult expert companies or professionals.
Distillation, the mash now contains about 10% alcohol and 90% non fermentable solids, the solids are now separated from the alcohol, to reach about a 96% strength of alcohol.
Dehydration, is where the last of the water is removed to make the alcohol about 200 proof.
Denaturing, is used then to make the alcohol unfit for human consumption, this is done by adding a small amount of gasoline, like 2-5%.
There are 2 co products derived from this process as well. The first is the non fermentable product, this is used as a livestock feed, the second is the carbon dioxide which is collected from the process and sold to other industries.
There are many reasons to use Ethanol as either an additive or an alternative fuel; one of the main reasons is the reduction of pollution. Regular fossil based fuels are not only damaging to the environment they are a non-renewable resources; once they are gone they can never be replaced, or regenerated.

What is Biofuel?
What is Biofuel? (also called agrofue) It can be broadly defined as solid, liquid, or gas fuel consisting of, or derived from biomass. The definition used here is narrower: biofuel is defined as liquid or gas transportation fuel derived from biomass. Biomass can also be used directly for heating or power: this is commonly called biomass fuel: see biomass heating systems. Biofuel is considered a means of reducing[2] greenhouse gas emissions and increasing energy security by providing an alternative to fossil fuels.
That is why biofuels are used globally: biofuel industries are expanding in Europe, Asia and the Americas. The most common use for biofuels is in automotive transport (for example E10 fuel). Biofuel can be produced from any carbon source that can be replenished rapidly e.g. plants. Many different plants and plant-derived materials are used for biofuel manufacture.
Humans have used biomass fuels for heating and cooking since the discovery of fire. Following the discovery of electricity, it became possible to use biofuels to generate electrical power as well. However, the discovery and use of fossil fuels: coal, gas and oil, have dramatically reduced the amount of biomass fuel used in the developed world for transport, heat and power.
Liquid biofuels have been used since the early days of the car industry. Nikolaus August Otto, the German inventor of the internal combustion engine, conceived his invention to run on ethanol. Rudolf Diesel, the German inventor of the Diesel engine, designed it to run on peanut oil. Henry Ford originally designed the Ford Model T, a car produced from 1903 to 1926, to run completely on ethanol. However, when crude oil became cheaply available (thanks to oil reserves discovered in Pennsylvania and Texas), cars began using fuels derived from mineral oil: petroleum or diesel.
