A new Liquid Chromatography Distillation (LCD) method was applied to determine Boiling Point Distribution (BPD) of heavy oils, which refer to the residual oil of petroleum, coal asphalts and coal direction-liquid residue, etc. Through a series of studies, the LCD method was established by the Size Exchange Chromatography (SEC) of liquid chromatography and the BPD of some typical heavy oils were determined. It is also reported that this method could be applied in other processes related with heavy oil, such as making high-level road asphalt, modification of coal liquefaction residues, and hydrogenation of heavy oil. In this paper, some other distillation technologies including hydrodistillation, molecular distillation and membrane distillation are also reviewed systematically.
