Biofuel Guide - Introduction to Ethanol and Biodiesel

Ethanol, as in beer and wine, is an alcohol modified to utilize it as a fuel and making it undrinkable. Ethanol is produced by fermentation through a method similar to beer brewing of any biomass containing carbohydrates. At the present time, ethanol is derived from starches and sugars however there have been constant research to allow it to be produced from fibrous substance which consists the bulk of most plant matter - the cellulose and hemicellulose. Ethanol is widely used as a blending agent with gasoline to boost octane and at the same time reducing carbon monoxide and other toxic smog-causing emissions.

In contrast to other renewable energy resources, biomass, an organic material, can be converted directly into burnable fuels, termed as “biofuels,” to assist in meeting transportation fuel demands. The two most widely used types of biofuels are ethanol and biodiesel.

On the other hand, biodiesel is produced by the combination of alcohol which is usually alcohol with vegetable or animal oil/fats, or recycled cooking grease. In order to lessen harmful vehicle emissions, it can be utilized on its pure form or as an additive (normally 20%) as a renewable substitute fuel for diesel engines.

Biodiesel and ethanol are both clean, grow-your-own fuels which can be produced on-site in local villages or communities from locally available, renewable resources, for the most phase using equipment that a local workshop can make and maintain. This can make biofuels an economical option to fossil fuels and can aid in strengthening local communities both socially and economically.

Cleaner burning energy sources lessen the toxic pollutant emissions produced by burning gasoline, and it cuts down on the dumping of used oil. Another gain is that many alternative fuels can be generated, while oil is a non-renewable resource. Demand varies, and there is always the possibility of discovering new reserves. In the contrary, fact remains that the supply may well run out one day. Present estimates predict that world oil production will reach its peak some time in the next 10 to 15 years. It thus makes sense to search for new alternatives before that day arrives. In addition, a much-hyped reason is that lessening dependence on oil will, in turn, reduce dependence on unreliable foreign oil.

Biofuel is made from agricultural crops developed in the different parts of the United States and other countries as well. Increased utilization of biofuel can generate new markets for American products. A number of jobs can also be produces especially in rural communities. As a result, it can keep the money circulating all the way through the domestic economy. Moreover, it promotes American energy independence just by generating a percentage of our fuel at home.

More importantly, biofuel is capable of improving the performance of your engine. Biofuel is a “quality” fuel that cleans your fuel system, increasing octane and lessening harmful emissions, all of which help to lengthen the life of your vehicle. As an alternative to this “traditional” diesel fuel, biofuel is expected to yield significant energy security and environmental advantage to its consumers.

How It Works

To generate biodiesel, the raw oil is subjected to a process called “transesterification.” This refining method uses of an industrial alcohol (ethanol or methanol) and a catalyst (substance that speeds up the chemical reaction) resulting to a conversion of the oil into a fatty-acid methyl-ester fuel (biodiesel).

It can be utilized in single pure form however it may require engine alterations to avoid maintenance and performance troubles. It is most commonly mixed with conventional petroleum diesel fuel at any level to reduce detrimental automobile emissions. When biodiesel is combined with petroleum diesel, it brings in a fuel that is compatible with diesel engines, reduce imported petroleum needs and decrease toxic emissions. A combination of 20% bio- and 80%- conventional diesel will greatly lessen carcinogenic emissions and gases which can worsen global warming. Lower-level biodiesel blends, such as 2% bio- and 98% diesel or 5% bio- and 95% diesel, are turning out to be increasingly common and widely used by the public as they become more aware of the many benefits.

Definition

Biodiesel is a renewable fuel made from farm products such as vegetable or animal oils, fats, or recycled cooking greases. Almost all biodiesels are derived from soybean oil; however sunflower oil, canola oil, recycled vegetable oils, and animal fats can also be used in the United States.

A Safe and Clean Fuel

• Cleaner Emissions – The use of biodiesel lessens greenhouse emissions because carbon dioxide that is released from the combustion of biodiesel is neutralize by the carbon dioxide utilized while growing the feedstock.

• Non-hazardous – In terms of toxicity, biodiesel is the best alternative that has proven to be safe and not harmful to the environment. Various tests verified that biodiesel is biodegradable and nontoxic that poses no threat to human health.

• Simple – The automobile need not any complex modification or conversion. The biodiesel can be readily blended with conventional petroleum diesel in your fuel tank at any point in time.

• Renewable – Biodiesel is derived from 85% vegetable or animal oils/fats which are renewable sources.

• Sustainable – Aside from it biodegradability, biodiesel is also renewable in contrast to scarce fossil fuel use which is formed from the remnants of animals and plants that have lain in the earth for millions of years.

• Nonflammable – In contrast to gasoline which ignites immediately at any lower temperature, biodiesel will only ignite at a very high temperature.

• Appropriate for Your Engine – A number of tests reveal that biodiesel is more lubricating than any conventional diesel to both the fuel injection pump and engine.

• Available – Currently in the United States, there are roughly 600 fleets that use biodiesel blends in their diesel engines. Moreover, various blends of biodiesel at approximately 800 areas are available nationwide.

• Affordable – The geographic area, base organic material (soybean, corn, etc) and supplier will greatly determine the price of biodiesel. It varies depending on the said determinants. It does not also require purchasing new vehicles to shift from conventional diesel to biodiesel. On the side of the fleets, acquisitions of new spare parts supply or rebuilding stations need not to be done by the manager.
