BIODIESEL
Biodiesel refers to a vegetable oil or animal fat based diesel engine fuel consisting of long chain alkyl ethyl methyl or propyl esters. biodiesel is typically produced by a chemically reacting lipids e.g., vegetable oil animal fat with an alcohol. why diesel is meant to be used in standard diesel engines full stop it is distinct from the vegetable and waste oil used in fuel converted diesel engines. biodiesel can be used alone or blended with petro-diesel. biodiesel can also be used as a low carbon alternative to heating oil. blends of biodiesel and conventional hydrocarbon based diesel our products most commonly distributed for use in the retail diesel fuel market place. much of the world uses a system known as the B factor to state the amount of biodiesel in any fuel mixture.
1. 100% biodiesel, zero percent petrol diesel is labelled B hundred
2. 20% biodiesel, 80% Petrol diesel is labelled b20
3. 5% biodiesel 95% petrol diesel is labelled B5
4. 2% biodiesel, 98% petrol-diesel is level B2
Blends less than 20% biodiesel can be used in diesel engines without any or with very minor modifications of blends less than 20% biodiesel can be used in diesel engines without any or with very minor modifications of the engine biodiesel can also be used in its pure Form B hundred but may require certain engine modifications to avoid maintenance and performance problems biodiesel can also be used in its pure form be hundred but may require certain engine modifications to avoid maintenance and performance problems. biodiesel can be blended with petrol diesel at any concentration biodiesel can be blended with petrol diesel at any concentration in most diesel biodiesel can be blended with petrol diesel at any concentration in most diesel engine injection pump. why diesel has been known to why diesel has been known to breakdown deposits of Residue in the few lines where Petrol diesel has been used. as a result fuel filters may get clogged with particulates if a quick transition to pure biodiesel is made. therefore it is recommended to change the fuel filters on engines and eaters shortly after first switching to a biodiesel blend. from the year 2005 biodiesel use has been increasing all over the world.
Production -
Biodiesel is commonly produced by the transesterification of the vegetable oil or animal fat feedstock . the following methods are usually adopted for carrying out his transesterification reaction:
1 common batch process
2 supercritical process
3 ultrasonic methods and
4 microwave methods
chemically transesterification biodiesel comprises a mix of alky mono alkyl esters of long-chain fatty acids. the most common form uses methanol to produce methyl esters. these are commonly referred to as fatty acid methyl Ester- FAME. higher alcohols such as isopropanol and butanol have also been used. higher molecular weight alcohols improve the cold flow properties of the resulting ester. however it is at the cost of a less efficient transesterification reaction. A Lipid transesterification production process is used to convert the waste oil to the desired esters. any free fatty acid in the base oil are either converted to shop and removed from the process or they are esterified using an acid catalyst. after this processing unlike straight vegetable oil why diesel has combustion property is very similar to those of Petroleum diesel and can replace it in most current uses.
As, by product of the transesterification process is the production of glycerol research is being conducted globally to use this glycerol as a chemical building block. usually this crude glycerol has to be purified typically by performing vacuum distillation. this is weather energy-intensive. the refined glycerol 98% + purity then we utilized directly or converted into other products stop a variety of oils can be used to produce biodiesel. these include:
virgin oil feedstock at present rapeseed and soybean oil most commonly used it also can be obtained from field pennycress and jatropha and Aadhar crops such as mustard, flax, Sunflower oil coconut hemp etc.
pure plant oil or straight vegetable oil production of vegetable oils for use as fuels is theoretically limited only why the agricultural capacity of a given economy. however doing so detract from the supply of other uses of pure vegetable oil.
animal fats include tallow, lard, hello Greece korma chicken fat and the byproducts of the production of Omega 3 fatty acids from fish oil.
