| Abstract: | The progress in diesel oil refining technology was summarized. Emulsification appeared in the process of traditional alkali washing-electrofining. The current alkali washing-electrofining technology could be optimized by means of modifying the technological parameters, appending deemulsifier or low molecular weight naphthenic acids, Na_2SO_4 and alcohol and so on. To overcome the problems in traditional technology, the new technologies, solvent extracting, ammonia treating, adsorptive separating and microwave radiation methods were discussed to separate and recover naphthenic acids. The advantages and deficiencies of these methods were evaluated. . |
