Method for efficiently preparing PAO50 basic oil
2017
The invention provides a method for efficiently preparing PAO basic oil. The method is characterized in that after waste lubricating oil is refined, under the effects of a catalyst and a cocatalyst, peroxides are used as auxiliary agents; in the reaction time being less than 1.5 hours, the high-viscosity basic oil is synthesized. The invention aims at overcoming the defects. The method has the advantages that the low-viscosity PAO basic oil is used for synthesizing the high-viscosity PAO basic oil, so that the waste low-viscosity PAO basic oil can be regenerated and reutilized; economic performance and environment-friendly effects are achieved; in addition, in the method, the reaction time is shorter than that in the conventional process; the production energy efficiency is improved to a certain degree; the production cost is reduced.
