FY-14吸附剂用于大庆减三线润滑油基础油精制

THE REFINING OF VACUUM CUT 3 LUBE BASE OIL FROM DAQING WITH FY-14 ADSORBENT

采用有机酸改性活性白土FY 14吸附剂对大庆减三线润滑油基础油的脱氮效果进行详细考察,并与活性白土进行对比。研究结果表明,白土精制温度较高,在150℃时5.0%白土用量的碱性脱氮率为88.3%,而在100℃时2.5%FY 14吸附剂用量的碱性氮脱除率为95.6%,硫脱除率为13.2%,旋转氧弹值为268min。随着碱性氮脱除率提高,精制油折光率呈不断下降趋势。上述实验结果表明,采用FY 14吸附剂精制基础油可达到节能降耗、提高基础油收率和氧化安定性的效果。

The denitrogenation effects are investigated for the vacuum cut 3 lube base oil from Daqing by using the organic acid modified activated clay FY14 as adsorbent. The performances of activated clay and FY14 adsorbent are compared. The results show that the refining temperature of clay is higher. The removal rate of basic nitrogen compounds (BNC) is 88.3% with 5.0% of clay at the temperature of 150℃. The removal rate of BNC is 95.6% with 2.5% of FY14 adsorbent at the temperature of 100℃,and the removal rate of sulfur is only 13.2% and the rotating bomb time is 268 min.The refractive index of the refined oil decreases continuously with the increase of the removal rate of BCN. These experimental results indicate that using the FY14 adsorbent to refine the base oil can result in energy saving, consumption reducing, yield of base oil increasing and oxidation stability improving.
