摘要: 针对石蜡基减压渣油蜡含量高的特点,将其经溶剂脱沥青得到脱沥青油,再通过加氢处理-异构脱蜡-补充精制工艺得到加氢生成油,并将加氢生成油经减压蒸馏切割后得到高附加值润滑油基础油系列产品。研究结果表明:通过控制三段高压加氢深度及调整蒸馏切割温度,可生产出90BS,HVIH14,HVIH8,HVIH4,HVIH2 共5个牌号的润滑油基础油产品,以脱沥青油进料为基准时润滑油基础油总收率可达75%左右,以减压渣油为基准时润滑油基础油总收率约为34%,可实现减压渣油的差异化利用。

Abstract: High wax content paraffin-base vacuum residue was refined by solvent deasphalting process to obtain deasphalted oil, and then treated by hydrotreating-isodewaxing-hydrofinishing process, and vacuum distillation to obtain high value-added lube base oil series products. Research results showed that by controlling high pressure hydrogenation depth and adjusting the distillation cutting point, a series of base oils of 90BS, HVIH14, HVIH8, HVIH4, and HVIH2 could be produced. The total yield, based on deasphalted oil feedstocks, could reach around 75%, while total yield was about 34% based on vacuum residue. The differential utilization of vacuum residue can be realized.
Key words: vacuum residue, solvent deasphalting, high pressure hydrotreating, lubricating base oil
