T. Navin Prasad, G. Anbarasu Department of Mechanical Engineering, Sri Ramakrishna Engineering College, Vattamalaipalayam, Coimbatore, Tamil Nadu, India ABSTRACT Biodiesel is a renewable resource of energy, which helps to reduce the dependence on the limited economy resources available in the world. The present research work is an approach towards attaining price competency of biodiesel to petroleum diesel. Biodiesel either directly or blended with diesel fuel is widely investigated to reduce the depletion of fossil fuels and environmental degradation. There has been growing interest in alternative fuels like biodiesel, a best substitute fuel for internal combustion engines. This paper reviews the biodiesel from various resources, different methodologies used for biodiesel production and the properties of different biodiesel. Biodiesel is an eco-friendly, alternative diesel fuel produced from vegetable oils and animal fats. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a blended fuel (Diesel and Biodiesel) to reduce levels of particulates, carbon monoxide and hydrocarbons from diesel-powered vehicles. The main objective of this study is the development of biodiesel by various methods and fuel-related properties. Keywords: Alternate fuel, Bio-fuel, Biodiesel, Transesterification, Fuel Properties. I. INTRODUCTION Biodiesel is an alternative fuel from vegetable oil and animal fats, which could be edible or non-edible. Before the first diesel engine became functional, scientists E.Duffy and J.Patrick conducted the transesterification of a vegetable oil in1853. Rudolf Diesel invented the diesel engine in 1893, which first ran on peanut oil. Biodiesel has a high potentialas new and renewable energy resource in future. Without any modification in diesel engines, biodiesel can be used as a substitution fuel for petroleum diesel. Biodiesel is produced from edible and non- edible oils, but there may be a cause of negative effect on the world by using edible oils, such as depletion of food supply leading to economic imbalance. The biodiesel from non-edible oils such as Pongamia, Calophyllum inophyllum, Jatropha, Cebia petandra, karanja, waste cooking oil are the future sources of energy. Bio-fuels were discovered even before fossil fuels like gas, coal and oil. The U.S. has accepted Biodiesel as clean alternative fuel and at present, its production is about 100 million gallons. Biodiesel has better fuel properties and it can be used as fuel for diesel engines (as either B5-a blend of 5% biodiesel in diesel fuel or B20 or B100). However, blends up to 20% should not give any problems. Biodiesel can be used as an additive to diesel fuel in order to reduce the overall sulphur content to blend and to compensate for the lubricity loss due to sulphur removal from diesel fuel. The cost components of biodiesel are  Price of seed  Seed collection  Oil extraction  Transesterification of oil  Transport of seed and oil The benefits of using biodiesel as a fuel in diesel engines are:  Biodiesel is environment- friendly than other fuels like petrol or diesel.  Biodiesel is a clean fuel and more economic.  Biodiesel is a renewable source of energy unlike other natural resources like coal and petroleum.
