摘要
Among the different alternative fuels explored for replacing existing fossil diesel, biodiesel has emerged as the potential renewable energy. It is made from nontoxic, biodegradable, renewable sources such as refined and used vegetable oils and animal fats. The usage of refined vegetable oil is considered as uneconomical owing to the high feedstock price and its importance as food resources. Non edible oil such as Jatropha curcus is considered as a better replacement of refined oil; but they have a high FFA content which makes them unsuitable for biodiesel production in one step which is a drawback. Apart from conventional techniques for bio-diesel production, application of microwave and ultrasound are explored for better results compared to conventional methods.
