Biofuel – today

In today's world day in and day out we see fleets of cars, buses, two-wheelers and trucks on our streets.

There is nothing more important for a developing country like India than a good energy plan. Therefore biofuel is today's extreme need.
Well, what is this biofuel? In contrast to fuel based on products derived from the petrochemical industry, biofuel is based on raw material derived from living organisms and therefore can be classified as a renewable resource. Biofuel can be of microbial or of plant origin. Of the microbial biofuel products, three basic types are fuel alcohol, biogas which is also known as methane and hydrogen.
At present there are2 main markets for fuel alcohol, Brazil (Proalcohol) and U.S.A. (Gasohol) used either blended with petroleum or as 95% Ethanol) water mixture in purpose-built engines. Biogas is the term used for anaerobic methane production, a biochemical reaction in which CO2 is the ultimate electron acceptor producing either CO or CH4. Since both of these products are volatile they are relatively easy to obtain in pure form. Biological hydrogen production is done mostly during nitrogen fixation.
Biofuel has millions of uses as well. One of thefirst benefits Rudolph Diesel a german engineer said," The use of vegetable oils for engine fuels may s
