| 中文摘要: |
| 采用中试装置，以石蜡基减四线馏分油为原料，评价两个催化剂级配方案生产高品质润滑油基础油的可行性。结果表明：采用三段高压加氢工艺的A催化剂级配方案，可得到满足Q/SY 44—2009指标要求的5cst及10cst润滑油基础油，在选定的试验条件下收率分别为17. 96%和45. 14%，280～360 ℃馏分无法满足2sct润滑油基础油的指标要求，但可作为变压器油基础油；采用三段加氢工艺的B催化剂级配方案，可得到满足指标要求的润滑油基础油，在选定的试验条件下2cst，5cst以及10cst润滑油基础油的收率分别为9. 01%，14. 56%和37. 17%。 |

| The feasibility of producing high-quality lubricating base oil with two catalyst schemes was evaluated by using a pilot plant and minus fourth-line distillate oil as raw material.The results showed that，by using catalyst scheme A of three-stage high-pressure hydrogenation process，5cst and 10cst lubricating base oils which met the index requirements of Q/SY 44—2009 were obtained under the selected conditions，their yields were 17. 96% and 45. 14%，respectively，but the 280～360 ℃ fraction could not met the index requirements of 2sct lubricating base oil，and it could be used as the base oil for transformer oil.By using catalyst scheme B of three-stage hydrogenation process，the obtained lubricating base oils met the index requirements，and under the selected conditions，the yields of 2cst，5cst and 10cst lubricating base oil were 9. 01%，14. 56% and 37. 17%，respectively. |
