Abstract: Biodiesel has become more attractive since one decade because of limited fossil resources and increasing demand for diesel. Biodiesel derived from vegetable oils/animal fats triglycerides is a worthy replacement for the hydrocarbon based diesel fuels, because of its multiple benefits, and it can be used in diesel engines without any modification in the existing engines. Transesterification is the most commonly used method for the production of biodiesel from vegetable oils and animal fats in presence of catalytic NaOH/H2SO4 at 70oC. The transesterification of these oils is affected by the mode of the reaction, molar ratio of the glycerides to alcohol, type and quantity of catalyst, reaction temperature, reaction time and purity of oil and fats. Cost of biodiesel thus obtained is the main obstacle in its commercialization. Efforts are under way in many countries to search options to reduce cost of biodiesel production. Other methods for the preparation of biodiesel with different combination of oils and catalysts have also been summarized. Biodiesel standards provided by different countries are given.
