Bio-diesel
is a diesel fuel substitute produced from renewable sources such
as vegetable oils, animal fats, and recycled cooking oils. Chemically,
it is defined as the mono alkyl esters of long chain fatty acids
derived from renewable lipid sources. The concept of using vegetable
oil as a fuel dates back to 1895 when Dr. Rudolf Diesel developed
the first diesel engine to run on vegetable oil. Diesel demonstrated
his engine at the World Exhibition in Paris in 1900 using peanut
oil as fuel.
The physical and chemical properties of Bio-diesel are similar to those of petroleum diesel; moreover, it is environmentally friendly, non-hazardous and bio-degradable. The applications of Bio-diesel range from transport vehicles to farming equipment to industrial machinery. Bio-diesel can be used in any type of diesel engine in a blend with petroleum diesel. No engine modifications are required for blends up to 10%. Bio-diesel can also be used “neat”, provided its viscosity is similar to that of petroleum diesel. The process to extract the viscous glyceroids from Bio-diesel is known as Transesterification. |
