【摘要】：基于气相色谱/质谱联用仪(GC/MS)建立了柴油中双环倍半萜烃指纹化合物的定性定量分析方法,并运用所建方法对催化裂化柴油、加氢裂化柴油、直馏柴油中的双环倍半萜类化合物进行了分析。结果表明,3种柴油中均含有双环倍半萜类化合物,由于原料和加工条件的不同,不同工艺来源的柴油间双环倍半萜类化合物的含量和分布有很大差别;相同工艺来源的柴油间双环倍半萜类化合物含量不同,分布相近。通过对双环倍半萜类化合物的分布特征及特征比值的分析,可以对催化裂化柴油、加氢裂化柴油、直馏柴油进行区分。
[Abstract]:Based on gas chromatography-mass spectrometry (GC / MS), a qualitative and quantitative analysis method of dicyclic sesquiterpene hydrocarbon fingerprint compounds in diesel oil was established, and the method was applied to catalytic cracking diesel oil and hydrocracking diesel oil. The dicyclic sesquiterpenes in straight-run diesel oil were analyzed. The results showed that all three diesel oils contained dicyclic sesquiterpenes, due to different raw materials and processing conditions. The content and distribution of dicyclic sesquiterpenes in diesel oil from different process sources are very different. The content of dicyclic sesquiterpenes in diesel oil from the same process was different and the distribution of dicyclic sesquiterpenes was similar. By analyzing the distribution characteristics and characteristic ratios of dicyclic sesquiterpenes the catalytic cracking diesel oil could be obtained. Hydrocracking diesel oil and straight-run diesel oil are distinguished.

【正文快照】： 随着石油资源的日益匮乏以及“分子炼油”概念的提出,人们越来越关注石油的分子组成[1]。生物标志物是石油中一类很重要的烃指纹化合物,它们具有很强的稳定性,因而在经历了长期的演化过程后仍保留了母体的基本骨架结构,可以指示石油的有机质来源和原始环境;而其发生的某些官能，
