What is bio-Diesel ? How can it be manufactured ?
Ans :Bio-diesel is an eco-friendly, alternative diesel fuel prepared from domestic renewable resources i.e. vegetable oils (ediable or non- ediable oil) and animal fats. These natural oils and fats are made up mainly of triglycerides. These triglycerides when reacted chemically with lower alcohols in presence of a catalyst result in fatty acid esters. These esters show striking similarity to petroleum derived diesel and are called “Bio-diesel”. As India is deficient in edible oils, non-edible oil may be material of choice for producing bio diesel . For this purpose Jatropha curcas considered as most potential source for it. Bio diesel is produced by transesterification of oil obtains from the plant.
