以辽河、新疆、胜利、大庆原油和含硫油的润滑油馏分为原料 ,采用加氢技术制取润滑油基础油。中型试验结果表明 ,采用高压加氢处理、溶剂精制 -中压加氢处理技术 ,配以溶剂脱蜡可以制取氧化安定性好的 HVI润滑油基础油 ;采用加氢处理 /加氢异构脱蜡 /加氢补充精制工艺 ,制取氧化安定性和低温流动性好的 HVI和 VHVI润滑油基础油也是可行的。与传统润滑油生产工艺相比 ,加氢法具有目的产品收率高、质量好等优点。
Liaohe, Xinjiang, Victory, Daqing crude oil and sulfur oil-containing lubricating oil distillate as raw material, the use of hydrogenation technology to prepare lube base oil. The results of the medium-scale test show that HVI lubricating base oil with good oxidation stability can be obtained by using high-pressure hydrotreating, solvent refining-medium pressure hydrotreating combined with solvent dewaxing. Hydrotreating / hydroisomerization Wax / hydrotreating and refining process, to prepare oxidation stability and low temperature fluid HVI and VHVI lubricating base oil is also feasible. Compared with the traditional lubricating oil production process, the hydrogenation method has the advantages of high yield of the target product and good quality.
