Interconversion of distillation curves

The ASTM D86 distillation of an oil fraction takes place at laboratory room temperature and pressure. Note that the D86 distillation will end below an approximate temperature of 650 °F (344 °C), at which petroleum oils begin to crack at one atmospheric pressure. [Pg.7]

There are two specific octane numbers in use. The motor octane number (MON) reflects the engine performance at highway conditions with high speeds (900 rpm), while the research octane number (RON) corresponds to the low-speed city driving [Pg.7]

The cetane number measures the ease for self-ignition of a diesel fuel sample and is essentially an opposite of the octane number. It represents the percentage of pure cetane (n-hexadecane) in a blend of cetane and alpha methyl-naphthalene that matches the ignition quality of a diesel fuel sample. This quality is important for middle distillate fuels. [Pg.8]
