摘要? 潤(rùn)滑油是一種高附加值的石油產(chǎn)品，其種類繁多,，用途廣泛,。如何利用不同來(lái)源、性質(zhì)的原料生產(chǎn)出理想的潤(rùn)滑油產(chǎn)品是煉化工藝優(yōu)化需要重點(diǎn)攻關(guān)的難題,。對(duì)潤(rùn)滑油生產(chǎn)過程中的產(chǎn)品組成進(jìn)行分析可以為工藝優(yōu)化提供重要依據(jù),，但目前宏觀層面的性質(zhì)分析已經(jīng)很難指導(dǎo)日趨復(fù)雜的工藝優(yōu)化。本文針對(duì)遼河石化的潤(rùn)滑油產(chǎn)品及生產(chǎn)工藝特點(diǎn),，依托超高分辨率質(zhì)譜建立了一套全面、深入的分子組成分析方法,，從分子水平對(duì)潤(rùn)滑油加工的原料,、產(chǎn)品組成及其轉(zhuǎn)化過程進(jìn)行深入分析，解析加工工藝過程中的分子走向,，總結(jié)含氮,、含氧、含硫雜原子化合物的脫除規(guī)律,，從分子水平為定向工藝優(yōu)化提供了重要依據(jù),。

Abstract：

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.

Key words： petroleomics; ultra-high resolution mass spectrometry; molecular composition analysis; lubricating oil; hydrotreating; heterogeneous dewaxing
