Biodiesel emissions

Biodiesel energy as a renewable energy source can be generated from biodiesel. Biodiesel is a biofuel or non petroleum based fuel that can be manufactured from vegetable oil or animal fats. The bio diesel used as one of the biodiesel energy products may or may not emit particulates into the atmosphere.

Biodiesel energy products emit various particulates into the atmosphere when biodiesel energy is used.

Small amounts of hydrocarbons that cause smog are emitted by biodiesel energy products. But smog formation by these emissions is too less to be noticed. The use of biodiesel energy products does not emit sulfur oxides and sulfates which are the main cause of acid rain. Biodiesel energy products also do not emit pollutants. The use of bio diesel as an alternative energy source results in substantial reductions in the emissions of unburned hydrocarbons, carbon monoxide and other particulate matter. The use of biodiesel energy products emits very small amounts of carbon monoxide. This amount is also negligible and does not harm the environment and also does not cause any health hazards. Biodiesel energy when used does not emit particulate matter that can cause breathing problems. Biodiesel energy products may emit large or small amounts of nitrogen oxides depending upon the type of engine and testing procedures that are used. The nitrogen oxide emissions are increased on an average by ten percent if pure bio diesel is used as a biodiesel energy product.

Biodiesel and water

Biodiesel as a renewable energy source is non petroleum based fuel that is used to generate bio diesel energy. Biodiesel has a property that it is immiscible in water and this property helps in the production of biodiesel energy easily. Also biodiesel is hygroscopic which means that it can absorb atmospheric moisture and although this moisture is present in a small quantity it may create several problems when using bio diesel energy.

Several problems are encountered in the use of biodiesel energy products if the biodiesel that is used contains water. The combustion properties of biodiesel are reduced when water is present in it. This results in the generation of more smoke and less power from biodiesel energy products. When biodiesel energy products containing water are used to run diesel engine vehicles, they can corrode fuel pumps, fuel lines, injectors etc. Paper element filters may rot and can cause the failure of fuel pump system if water is present in bio diesel.

The freezing of water at zero degrees can form crystals that increase the gelling of biodiesel. The fuel system of a diesel vehicle that is powered by biodiesel energy products can get plugged if the biodiesel has water content in it. This can even damage the pistons of diesel engines.

Because the use of biodiesel energy is becoming very popular as an alternative energy source methods have to devised to overcome the problems caused by water content in biodiesel. These problems can be overcome by generating this form of energy by mixing products like petroleum, gas and kerosene.

Biodiesel Energy Products

Biodiesel energy is the energy obtained from biodiesel which is a renewable energy source. Biodiesel as a renewable energy source is non petroleum based diesel fuel. It is manufactured by the process of transesterification of vegetable oils or animal fats. Biodiesel as a biodiesel energy product is used mainly in diesel engine vehicles.

The concept of biodiesel energy as an alternative energy source has been in use for many years now. Biodiesel energy can also be made from soya bean oil and yellow grease.

The biodiesel fuel used as a biodiesel energy product can be used as a fuel or it can be mixed with petroleum to be used as a fuel. If the biodiesel fuel is mixed with petroleum, it is given a number which indicates the amount of petroleum mixed with bio diesel. The number B100 indicates pure bio diesel fuel without any mixed ingredient in it. But when pure biodiesel energy products are used in vehicles, it may cause a few performance problems. The problems arise because the engine may not be able to tolerate so much concentration of biodiesel.

Biodiesel energy products
when used for running trains are safe and effective energy resources. The biodiesel can also be used in airplanes and can be used for domestic purposes like heating homes which help in the reduction of electricity used.
Biodiesel energy products can be used anywhere in the world to generate biodiesel energy because soya bean can be grown in any part of the world.

Biodiesel energy production

The production of biodiesel energy by using biodiesel energy products has increased manifold in the last decade. The main reason for this is that bio diesel used for generating biodiesel energy is a clean, reliable, environment friendly and a renewable energy source.

The biodiesel that is used to generate bio diesel energy is basically made from vegetable oil. Many different types of oils are available for the production of bio diesel. The most common ones are soya bean and rapeseed oil which account for almost ninety percent of the biodiesel production. Waste vegetable oil, animal fats like lard, yellow grease, algae which can be grown using waste products like sewage, oil from halophytes and waste fish oil are the other biodiesel energy products that can be used for generating biodiesel energy.

Bio diesel is produced by the process of transesterification of vegetable oils or animal fats. This process of transesterification can be carried out by several methods like batch processes, supercritical processes, ultrasonic methods and microwave methods. The process of transesterification is a cost effective method of producing biodiesel energy products. The by products of this process is glycerol. The biodiesel energy products obtained from such a process has combustion properties. The process from which biodiesel energy products are produced has the advantage of being a clean and non polluting method of biodiesel production.

Biodiesel energy production has increased across the world because it can be easily used as an alternative energy source to meet the growing energy needs.

Biodiesel energy

Biodiesel energy is the energy obtained from natural biodiesel. Biodiesel is a fuel that can be made from waste vegetable oil. The waste vegetable oil is considered to be the best source of biodiesel although other sources can be used to manufacture bio diesel.

The other sources that can be used to make bio diesel are virgin oil feedstock, rapeseed oil, soya bean oil, oil from crops like mustard, palm and hemp. Algae are another source from which biodiesel can be derived. It can also be produced from animal fats like tallow, lard and yellow grease. Bio diesel can also be manufactured from non edible oils like Jatropha, neem oil and castor oil.

The biodiesel so produced can be used in the form of energy called biodiesel energy. The use of biodiesel energy can be made in place of fossil fuels. This means that biodiesel energy can be used as an alternative to fossil fuels that are decreasing in quantity all around the world. Fossil fuel reserves are depleting because the energy demands are increasing and they are at present the only sources on which there is maximum pressure to meet the energy requirements. Also fossil fuels cause a lot of pollution when they are burnt. Biodiesel energy on the other hand is a renewable source of energy that will never finish and will always be readily available for use. The use of biodiesel energy is also healthy for the environment.
