Abstract

The energy needs of the world have been increasing since the inception of the Industrial revolution. The major sources of energy throughout the world have been fossil fuels, namely coal, petroleum fuels and natural gas. These resources are limited and are depleting fast. The replenishment of these is not possible keeping in mind our enormous requirements of energy, as these are non-renewable. Hence, there is a need of energy sources which are renewable, economic and do not pose a major threat to the environment. Biodiesel fuels have emerged as an option that is renewable and economic. These fuels are used as blends with diesel and can be used to power CI engines. There is a large quantity of used cooking oil that is produced from household, restaurants, etc which is disposed off with no option of reuse. This type of waste oil is available in large quantities and at an economic rate. Thus, if used to create biodiesel, these types of oils can solve two problems “ it will give us an economic option of alternative energy resource that is easily available, and will help control environmental pollution that is caused by disposal of these waste oils on land and water resulting in destruction of flora and fauna. In this present review work, we have studied various works done in the field of biodiesel production from various sources and method by researchers around the world. This review work focuses primarily on two aspects: study of biodiesel production by various processes with special focus on trans-esterification process and study of performance/emission characteristics of VCR engines using different blends of biodiesel with normal diesel.
