摘　　要：润滑油是一种高附加值的石油产品,其种类繁多,用途广泛。如何利用不同来源、性质的原料生产出理想的润滑油产品是炼化工艺优化需要重点攻关的难题。对润滑油生产过程中的产品组成进行分析可以为工艺优化提供重要依据,但目前宏观层面的性质分析已经很难指导日趋复杂的工艺优化。本文针对辽河石化的润滑油产品及生产工艺特点,依托超高分辨率质谱建立了一套全面、深入的分子组成分析方法,从分子水平对润滑油加工的原料、产品组成及其转化过程进行深入分析,解析加工工艺过程中的分子走向,总结含氮、含氧、含硫杂原子化合物的脱除规律,从分子水平为定向工艺优化提供了重要依据。Lubricating oil is a high value-added petroleum product with a wide variety of application. It’s a challenging task to make full use of raw materials with various properties from different sources to produce the ideal lubricant products. Composition analysis at molecular level, instead of general analysis of physico-chemical properties, provides a deep view for processing optimization. In this study, comprehensive and in-depth analysis of molecular composition was established for characterization of lubricant products obtained by different processing conditions using ultra-high resolution mass spectrometry. Based on the molecular characterization of both feeds and products, the change of compound distribution was monitored during the conversion process, and the mechanisms of removal of nitrogen, oxygen and sulfur-containing compounds were summarized, which set a stage for process optimization.
