Biodiesel Purification and Upgrading Technologies

Abstract

Oil from grain can be easily converted into biodiesel, a green and sustainable fuel, via direct use and blending, microemulsions, thermal cracking, and transesterification, among which the latter is currently the preferable pathway as it overcomes the shortcomings existing in the former three. There are many parameters affecting the yield of biodiesel when prepared from grain oils. In view of sustainable development and environmental conservation, huge volumes of biodiesel from grain oils will be needed in the future of mankind. It is established that the combustion of biodiesel emits little pollution. Moreover, it is renewable.
