针对糠醛润滑油精制系统中抗氧化性能差的缺点,在糠醛中加入抗氧剂DBPC,并在小型间歇式和连续式抽提装置中对大庆原油润滑油馏分进行试验,得出添加DBPC的最适宣浓度为0.040W%.同单纯糠醛溶液抽提相比,在保证或改善精制油质量的前提下,精制油收率分别提高了6.97%(间歇式)和4.41%(连续式),且降低了溶剂比,减少能耗15.3%.本文还对抗氧化剂的作用机理进行了探讨. In view of the shortcomings of poor oxidation resistance in the furfural oil refining system, DBPC was added to furfural and the Daqing crude oil lube fraction was tested in a small batch and continuous extraction unit. The declared concentration was 0.040W%. Compared with the pure furfural solution extraction, the yield of refined oil increased by 6.97% (intermittent) and 4.41% (continuous) respectively, while ensuring or improving the quality of the refined oil, and Reduce the solvent ratio, reduce energy consumption by 15.3% .This paper also discussed the mechanism of action of antioxidants.
