Use of biofuels in the transport sector is on the rise considering limited available fossil energy resources, the environmental issues associated with the use of fossil fuels and attention to the security of supply. In this presentation, we discuss properties that are important for the quality of fuels and the environmental emissions for both petrofuels (such as diesel fuel) and biofuels (such as biodiesel). These properties include density, distillation temperature, viscosity, pour point and properties related to cold weather, vapor pressure, solubility, carbon residue, elemental composition, acid content, cetane index, the heating value or energy content and the C/H ratio. In addition, we discuss factors that affect the quality of biofuels, such as the composition of raw materials and processing methods as well as the blending of bio and petrofuels. Finally, a comparison is made on the environmental impacts and the emissions from an internal combustion engine when a biofuel or petrofuel is used especially on the CO, CO2, NOx and sulfur emissions.
MR Riazi is currently professor of chemical engineering at Kuwait University. He was previously a faculty member of chemical and petroleum engineering at various universities in US, Canada, Europe, and the Middle East. He has published extensively including 6 books on petroleum and biofuel properties and processing technology. He is the founding editor and editor in chief of IJOGCT (London, UK) and an editor of the Journal of Petroleum Science and Engineering (Elsevier). He is an elected Fellow of the American Institute of Chemical Engineers (AIChE) and is a licensed professional engineer in Ontario, Canada (P.Eng.).
