Although there are many types of biofuels in the forms of gaseous (such as biomethane or biohydrogen) as well as in liquid and solid forms but the two types of biofuels that have been commercialized are biodiesel and bioethanol and both are in liquid forms. In addition to regular biodiesel produced from alcohols, biodiesel can be produced from hydrotreated vegetable oil (HVO) which hydrogen is used as a catalyst to convert vegetable oil to biodiesel . Properties of these biofuels (produced from different paths and different raw materials) are compared with specifications of different petrofuels such as gasoline, diesel, jet fuel, and light gas-oil used as transportation fuels. Physical properties (ie, density , boiling range and transport properties ), thermal properties (ie, heating value, heat capacity), properties related to engine performance (cetane number, fuel consumption), safety (ie, flash point), cold conditions (pour point), fuel quality (ie, H/C ratio, aromatic, sulfur and oxygen contents) as well as fuel impacts on the environment (ie, CO, NO and sulfur emissions) are discussed in this presentation.
