以中海油某炼厂加氢裂化装置尾油为原料，采用该炼厂石蜡基润滑油加氢装置异构脱蜡-补充精制段反应器现用催化剂，进行异构脱蜡-补充精制试验，考察了不同反应温度下生产高档润滑油基础油、化妆品级白油、食品级白油的可行性。结果表明，不同反应温度下均无法制备出高黏度指数（>100）且倾点合格的润滑油基础油；在反应压力15 MPa、空速1.0 h^-1、氢油体积比800：1、异构脱蜡和补充精制段反应温度分别为330、240℃条件下，加氢生成油300~380℃馏分段（收率18.48%）和>380℃馏分段（收率36.79%）分别可以达到食品级白油（GB 1886.215—2016）、化妆品级白油（NB/SH 0007—2015）产品指标要求。

Taking hydrocracking tail oil from a refinery of CNOOC as raw material,isomerization dewaxing and supplementary refining test are performed over the catalyst in service to investigate the feasibility of producing high-grade lubricating base oil,cosmetic-grade white oil and food-grade white oil at different reaction temperatures.The results show that the base oil with high viscosity index (>100) and qualified pour point cannot be prepared at any reaction temperatures.The distillate at 300-380℃ (a yield of 18.48%) and the distillate exceeding 380℃ (a yield of 36.79%) can respectively meet the product index requirements of food-grade white oil (GB 1886.215—2016) and cosmetics-grade white oil (NB/SH 0007—2015) when reaction pressure is 15 MPa,space velocity is 1.0 h^-1,the ratio hydrogen to oil is 800:1 and the temperatures of isomerization dewaxing and supplementary refining sections are 330℃ and 240℃,respectively.
