Biodiesel

What's the Biodiesel?

Biodiesel is a renewable fuel derived from vegetable oils or animal fats. It is defined as mono alkyl asters of long chain fatty acids derived from renewable fatty inputs such as vegetable oils or animal fats. As a fuel, biodiesel can be used in pure or mixed with petroleum diesel form.

Produccion del Biodiesel

The biodiesel production process is based on the transesterification reaction of the oil. The oils are composed primarily of molecules called triglycerides, which are composed of three fatty acid chains attached to a glycerol molecule. Transesterification involves replacing glycerol by a simple alcohol such as methanol or ethanol, so that metal or ethyl fatty acid asters occur.

To achieve the reaction temperatures must achieve between 40 and 60 Celsius, and the presence of a catalyst, which can be caustic soda or potash are required.

The physicochemical characteristics of biodiesel are similar to petroleum diesel. As a result, its use does not require major changes in conventional diesel engines.

Biodiesel can be pumped, stored and handled with the same procedures, infrastructure and equipment used diesel.

Ventajas del Biodiesel

Best Combustion

The structure has oxygen molecules that allow the engine to perform a complete combustion and therefore has a better fuel efficiency. Having better combustion the amount of emissions is reduced.

It makes easier a cold start

The low cetane is directly related to difficulties and delays in the ignition, smoke, reduced strength and reduced mileage. Cetane improvement will reduce the ignition timing .. The cetane number of biodiesel is higher than diesel so it helps the engine.

Reduce emissions

The black smoke from the exhaust of vehicles is due to the issuance of evil burned diesel, ie of inadequate combustion. Proper combustion helps reduce emissions because the fuel is burned in its entirety.

Reduces wear to increase fuel lubricity

Protects the motor from accelerating descaste injection pump and injectors because it ensures better lubricity.

Non-toxic

Non-toxic, the handling it's safer than diesel, as a comparative point can be taken that is nearly 100 times less toxic than diesel and is 10 times more toxic salt biodiesel. Its toxicity is so low that a person of 80 kg should take about 1.6 liters of biodiesel to have deadly effects.

Clean Fuel System

Due to its high solvent and detergent, biodiesel remove all trash and sometimes some painting of tanks and pipes in those diesel engines used always and suddenly start using biodiesel, forcing initially periodic filter cleanings made out of fuel.

High flash point

The flash point of biodiesel is higher than diesel so its management is easier and safer product. But as always, the security recommended measures when a flammable substance it's used to prevent accidents should be consider.

It is biodegradable

It is highly biodegradable in water, is a 100% ecological fuel that does not damage the environment because it is composed entirely of plant products. It can be produced from local inputs such as oil crops or recycled vegetable oils, helping to reduce dependence on oil imports, saving foreign exchange and creating jobs.

It contributes to the Global Warming Reduction

It emits less CO2 in their life cycle than that fixed by the process of photosynthesis by plants used to produce it. On the other hand, it prevents carbon release set million years ago in the fossil fuels.

It has no sulfur

Sulfur diesel has one of the most important pollutants, leaving the car exhaust and sulfur oxide (SOx) which moisture is converted into sulfuric acid, which subsequently contribute to the generation of acid rain. The biodiesel has a good lubricating power which helps to prevent wear due to lack of lubrication, also it contains no sulfur.

Clean and helps maintain clean injectors and valves

Kept free of deposits and dirt on the engine injector system to help reduce harmful emissions (CO / HC / NOx) and particulate matter; this provides better combustion.
