چکیده انگلیسی
The conventional deacidification methods have many disadvantages. In this paper, we reported a new method using microwave irradiation to remove the naphthenic acid from the vacuum cut #1 distillate oil of Daqing. When the distilled oil (the volume rate of solvent-to-oil was 0.23:1) was irradiated for 5 min under constant pressure (0.11 MPa), and then rested for 25 min, the acid number was reduced from 0.63 mg KOH/g to 0.0478 mg KOH/g, which was sufficient to meet the specification of Q/SHR001-95 (less than 0.05 mg KOH/g) on lubricating oil, and the recovery rate of the distilled oil was 99.3%. The microwave irradiation method has many advantages, such as, it is highly effective, it consumes less time and it is environmentally friendly.
